Move out but stay together or just leave?

So my boyfriend and I have a 3 month old and 2 dogs

We are tired and we are bickering a lot and there have been several big arguments lately I’m so fucking sick of it I do still love him…but I don’t feel like I want to marry him anymore and that was always the plan… but the plan was also to get married before kids… I don’t feel like he wants to be around me anymore and I miss when he actually gave a shit and wanted to hang out with me… wanted to talk to me about stuff… I’m thinking about suggesting that I move out and we split the time with our son (the dogs would go with the baby?) 50/50.. one of us gets the baby sun-Tue and 1/2 the day on Wednesday and then the other person gets him the rest of the days…. And then we can see each other when we want to…not because we have to….

What do you think? Horrible idea? Good idea? Or should I just leave and do the 50/50 thing… he is a good dad.. I think I just want to see him make an effort again and I want to feel like I matter… idk maybe this has just run it’s coarse…

Update

So the arguments are usually about him on the computer or Xbox or both from the second he wakes up until he goes to bed… he has been talking to the same girl on Xbox for a few weeks now and he has been bringing up sexual topics with her.. and has been telling her his life story they got really close in a few weeks because guess what they are both on Xbox all day together… I told him first of all I don’t bring up or talk about anything sexual with any other man because I am in a relationship and second I am not liking the emotional connection they seem to have and why is he on there all of the time with her making little nicknames for her and just weird shit, throwing sexual stuff out there at me in front of her to get my reaction and to get her answer of what she thinks about it..

He works for himself but work is sporadic but also says he doesn’t want me to miss out on our son being this little which I appreciate and I told him I don’t want him to miss out either but one of us if not both of us has to work. I worked as a dishwasher for the end half of my pregnancy. I was in a ton of pain all day. I would come home to him playing Xbox every day… I saved up enough to coast after baby was born but that is running out and I am doing side jobs for now but every time I bring up getting another job he says that working for minimum wage is not even worth working at all because you don’t make shit…. I have said a bunch of times well at least my shitty minimum wage job allowed us to coast since he was born… a job is a job kinda mindset…

I moved out here to be with him and we were living with his family for a year and a half.. we have had a few pregnancy losses so I understand waiting to tell everyone and also we had an apartment lined up but it got rented out to someone else at the last second and we couldn’t afford anything else.. and he wanted to hide the pregnancy the entire time so “he didn’t have to hear the bitching”. At 19 weeks I had gotten the ultrasound pictures printed and crocheted baby shoes and put them in a box as the pregnancy announcement but he didn’t want to tell them at all I would bring it up almost every day and he would just get pissed off.. so we hid the pregnancy for 36 weeks until I was showing too much to hide it anymore… which I felt like an absolute piece of shit to his family and I felt absolutely shit on because when I was throwing up he would tell me to be quiet from across the room.. I wasn’t allowed to talk about the pregnancy while at the house because “someone might hear us talking” so i would try to pull his ass away from the Xbox to get out of the house to talk about it and then he would say don’t worry about whatever you are worrying about it will work out the way it is supposed to or when i would research something and bring it up or try to talk about anything baby related he just didn’t really want to talk about it much… I wasn’t able to nest because we had to move the week before my due date

And we were at our storage units while I was in labor I had contractions all day and they were about 5 minutes apart for 3 hours I told him I was timing the contractions and they are close together and we might need to go to the hospital soon and he continued pulling stuff out of his storage unit…. My water broke at about 4:30 and I told him I think my water broke he told me “no that wasn’t your water breaking because it isn’t a ton of liquid” I said no it doesn’t work that way all the time that is just how it happens in the movies but he didn’t want to hear it so I continued to help move shit and pack shit up… while arguing and packing shit up the entire rest of the evening.. finally at 10:30 pm I decided to call the on call nurse because he was just not listening to me he kept telling me I will know when I am in labor…. I told the nurse what was going on that I think my water broke at 4:30 and she said Immediately “GO TO THE HOSPITAL”

Sure enough guess the fuck what I was in labor….

So there is a lot of stuff like that where I am holding resentment towards him and that isn’t gonna end well so I’m just at the point where if shit doesn’t drastically change then I’m done… I’ve been feeling thankful that I am not married to him…and a lot of times men change after you leave.. they don’t really change when you are with them.. then if you get back together with them they revert right back to whatever behavior it was before… so I don’t even want to try to “fix” any of this i feel so shit on this isn’t even my issue to fix and up until a few arguments ago he was completely oblivious to how I was feeling… even though I have tried to talk to him about it the entire time but I have been shut down…
