Am I going through a phase?

My bf and I split up in January. We were together for 8 years. During our relationship, I was all about him. My world revolved around him. Well it got to the point where he took advantage of that and started treating me like I was nothing. Fighting with me about everything, putting other people first and of course himself. He acted like he was single with the benefits of having a “wife” lol he would go out and make plans and just leave me at home. And no matter what I did, I felt like it was impossible to make him happy. I lost my self, I wasn’t close to my family anymore, I didn’t have friends, and over all I was just exhausted and unhappy. But for some reason I wanted to continue the relationship bc I love him and I wanted our family to work . Well, the last six month of our relationship was the worst, the arguments happened more frequently, I felt like I had to walk on eggshells around him and his kids. He would tell me mean things like his kids didn’t like me and we weren’t going to work out and how he just wanted to be single. Well I ended up getting my own place in January bc I couldn’t handle it anymore. During that time him and I still talked and saw each other bc of our son. At that point I still wanted to try to work things out and he would say the same so I would go stay with him at his house but if he didn’t get his way he would “break up” with me again. lol it happened a couple of times and I told him if he wants to be with me he had to come to my place and stay with me. I was tired of packing my stuff all the time and going back And forth . I know this sounds so toxic and probably is but I just wanted my family to work out, but only if he changes of course.

It’s been 5 months and he’s just now starting to try. He’s been at my place for about 3 days now. I see him trying and I’m grateful for that, but since he’s been here, I feel more stressed. He is honestly like having a second child. I don’t have my freedom anymore and I feel like I’m slowly starting to lose contact with my friends and family again. I didn’t go crazy or anything like go clubbing or go to bars, but I had girls night at the lake with my cousins and mom, even my son was there. It sucks bc during our relationship, he had his fun with his friends and family while I had to just stay home and take care of the kids. Now that’s out of his system, he wants to be with me and doesn’t want me to do anything . He wants me just to spend time with him and gets kinda jealous if I want to do anything without him. I feel bad bc now that he’s giving me what I’ve been asking for, I feel like it’s too late maybe? And I know maybe it’s only be three days so idk how long he plans to try for. He’s been bringing his stuff little by little and I don’t want to do the same thing he did to me and make him feel like he has to pick up and leave.

All I wanna do is be stress free and live my life. If someone invites me somewhere I want to be able to go if I want to and not have to come up with an excuse on why I can’t go. But is it worth losing my family bc I want to have fun?
