I need some advice...

So, here’s a little background. I’m so sorry this is going to be kind of long...

My boyfriend of almost 4 years and I had been constantly fighting the beginning of this year. We sat down and talked about ways that the year 2020 will be about us restoring our relationship and manifest into something beautiful again. We both talked about focusing on getting money to save back & a new place to live!

Well... January 20th 2020, I had found out I was pregnant. He felt he isn’t ready for a child, that we aren’t ready for a child. Financially or emotionally / physically. He also stated he didn’t know if he even wanted kids. He wanted me to get an abortion. Now... I’m pro-choice, but I never ever thought in a million years I’d ever get an abortion for myself (unless it was medically necessary or unfortunately rape.) I took it into consideration. Thought on it for a few weeks before my first ultrasound. I fell in love after I first heard the babies heartbeat. I couldn’t get an abortion. I told him this after my appointment. He was upset and told me he wasn’t ready to be a father yet, and that our relationship is going to be shit. We fought everyday up until March 19th. March 19th we got into a big argument (honestly forgot why we started to fight) he took his stuff and moved to his moms... His mom doesn’t like me whatsoever. She is a huge drunk and drinks from the time she wakes up till she goes to sleep. She will constantly get drunk and tell my boyfriend really really rude things about me. She went as far as telling my boyfriend that she can hook him up with his step sisters daughter knowing we’re still together and trying to work things out. We have talked several times about doing better and not fighting so we can be together and not have stress and dysfunction when the baby gets here. It’s been 2 months+ with the exception of him staying some nights and seeing if I’m okay and eating. He’s adjusting to the fact we are having a baby. We found out she’s a girl! And we picked out a name together. (His sister is very supportive of me and really likes me, she gives me advice about the baby and about her brother) well, I guess my question is.... how long is too long for him to finally come back? I feel as if his mom is trying so hard to destroy our relationship. His sister told me that their mom will do anything to control things and if she can’t she will destroy the situation. He has mentioned several times over the 2 months he is getting tired of her drinking so much and being there but he won’t tell me when he is planning on coming back. He just says “it’s not a forever thing. I don’t have a date or time but it’s not going to be months and years.” But it’s already been almost 2 and a half months. I’m 21 weeks and 3 days pregnant right now and I’m feeling so alone in all of this. I love him very much and I do realize how he feels about baby, but I even told him he didn’t have to stay. That I didn’t want to force or “trap” him into anything. He wanted to stay because he said he loves me and he doesn’t want to leave the baby fatherless and that he just wants us to work on things.

I just don’t know what to do... am I overreacting, is it just my hormones making me feel so alone? I’m holding onto hope but I don’t know how much longer I can continue going to sleep alone and waking up alone until he stays the night a few nights... it’s to the point I don’t want to have sex with him till he moves back fully back in... I don’t want to feel like he’s just getting sex from me and leaving... what do I do? 😭😭
