What should I do?!

I don’t think I want to be with my boyfriend anymore. We have been together for over 3 years,I was 18 nearly 19 when we got together. During that time we have been through quite a lot I moved in with him and his parents at the end of 2015, and I have been through a lot myself. In July 2016 we went on a break for about 3 months, and he told me to go back to my parents. At this time I was severely depressed, hated my life, I felt SO alone, was working a shitty part time job and relying on my boyfriend to make me feel better. I didn’t realise how bad it had gotten until we had an argument about him talking to another girl (only as a mate, but my paranoid head said otherwise). That day he slammed the door and went off to work and I broke down crying. I was supposed to go to work that day, but he sent me a text message saying that we should go on a break because he doesn’t know what he wants anymore and needs some space ect. For me this was the worst thing to hear, I was at rock bottom. I didn’t have a close relationship with my parents growing up, my mum was born with water on the brain which caused her slight brain damage so she can’t process things or show emotions the same way most people do. She wasn’t a ‘normal’ mum and I couldn’t talk to her about anything or show my emotions freely. So this obviously had a massive effect on me and was the root cause of my depression because my needs were not fulfilled growing up and I always felt like something was missing. Because of this I have been reliant on boyfriends and have been in two long term relationships since I was 14, the first one 4 years and the one I am in now. Anyway when he said he wanted to go on a break I was not stable mentally and told him that I had depression and I really needed him but he told me to go to my parents and didn’t want to see me. Being at my parents was dreadful, I felt so emotionally numb. My heart was aching all the time, I was holding back the tears when I was at work, I would sit in bed and just cry. I had no one. And he didn’t care. I was left in the dark about everything, he didn’t give me a straight answer about what he wanted. The waiting around for him drove me crazy, I just wanted to know where I stood. We talked a bit during our break and I slept over his quite a few times and had a few meals and a day or two out together, but it wasn’t a confirmation of wether we were back together properly. After a few months of getting used to being at home and enjoying my own company, in November I went with my boyfriend to get his tattoo for his birthday and spent a few days together and had a really good time. Then we started getting back on track and he wanted me to move back in, but I said maybe wait for a bit rather than rush back into things, but he really wanted me to move back in and I didn’t want to risk losing him so I moved in anyway. After that things were a lot better, but I was still depressed so I tried to get the help I needed. I got myself a new job at the end of November as a trainee dental nurse and did my theory test for driving. I went to a counsellor, I tried CBT, I tried group therapy for anxiety and depression, and finally went on 50mg of sertraline (Zoloft) in May 2017. Since then I was still suffering a lot, not happy with life and was on 50mg until about September when I started talking to my auntie who has also had depression and she told me to go up to 100mg. She was there for me everyday, texting me every morning to check I was ok and told me that I would get better. My boyfriend on the other hand even though I told him I was struggling and needed his support he wasn’t there for me like I needed him to be. When I told him I was unhappy and hated my life he said why you’ve got me and Frankie (our cat). But that wasn’t enough to make me happy. Anyway after months of talking to my auntie and going up gradually on my Zoloft to 200mg, I was getting better. So here’s the situation now. I feel like I have grown so much over the past year and am finally confident and independent in myself. I feel like a flower that has blossomed, but my boyfriend hasn’t blossomed with me. He is quite different from me, he doesn’t go out with mates on the weekends or after work or make the effort to get to know my family because he ‘hates people’. He doesn’t like my mum because of the way she is and never comes to family meals ect. When he comes home from work he’s all tired and grumpy and basically ignores me, then on weekends he’s a bit chirpier but doesn’t really want to go out anywhere. I suggest places for us to go or things to do but he says no to them. He doesn’t do anything to help me keep our bedroom tidy, he will throw his dirty clothes on the floor, he won’t put his clean ones away. He will leave rubbish in the room like McDonald’s, crisp packets, cake packets, empty coke and lucozade bottles. If he eats in our room he leaves the plates/dishes and doesn’t wash them up, same with glasses of squash ect. He will ask me to get him a drink or food if we’re in the room together because he can’t be arsed to get it himself and gets annoyed if I don’t get it for him. He doesn’t help with changing the bedding, hoovering, changing our cats littler trays or dusting the room. And he has some gross habits🤢he will pick his nose and wipe his bogies on the duvet or pillows, he doesn’t brush his teeth, and he picks his toe skin and like flosses in between them with his socks🤮. I put another post on here recently of a message I sent him about our relationship, and after a few days we made up, but didn’t actually talk about the whole situation. That’s the thing, whenever we have a fight he ignores me instead of talking it out after. And he’s never in the wrong, he will just sulk until I say sorry or show him attention and try and cuddle him and make up. Like with the post I put before, he made it feel like it was my fault, like my feelings weren’t valid. Then on Monday we were doing a food shop and as I was parking he was having a go at me because I wasn’t straight or in the lines saying ‘oh you can’t park’ ‘what are you doing your not even in the space’ ‘you’re not even in the lines’ so I said ‘yes because I can’t see them because they are really faint’ then he said ‘open the fucking window then’ so I just snapped and told him to shut up because it really wound me up. He shouldn’t be talking to me like that. He will make me feel dumb for asking stupid questions, or if I don’t hear what he said the first time I’ll ask what he said and then he’ll say why don’t you fucking listen. He drags me down, and I don’t need that. I’m at the point where I’d rather be single and have my own space and time to myself. I want to get to know myself even more and spend time with family and friends more, and just get out there. I really don’t know what to do, in my head I know it will be good for me, but in my heart I feel bad for wanting to leave him and the thought of doing it really hurts but I feel like I need the time to myself. I need time to be single. I have a better relationship with my parents now and I want to make that even stronger. Any advice would be much appreciated, sorry it’s long haha💗
