Can’t shake this Unhappiness

I’ve been with my boyfriend for 8 months now and for the past 2 months we’ve been fighting nonstop. I’ve talked with him about moving on and finding someone else that would make us happy and he’s not having it. He says he doesn’t want anyone else, that he wants to be with me and only me. I want to leave him, but I can’t. I know I will go back if he looks for me (which he will) so I’m trying to convince him that we tried and it just didn’t work out. I love this man immensely, but I’m just so unhappy with the way the relationship has been going. I haven’t met 2 of his daughters. The 2 he had with a girlfriend. The 2 he had with his ex wife I did meet. He hasn’t even told them about me which concerns me. I wonder if it’s because him and that ex are still intimate in some way?

I don’t feel he’s cheating. But you never know! Also, I haven’t met his parents. They’re religious so because he was married with his ex through the church, they view her as his partner even though they’re separated. They also don’t accept his 2 daughters from his other relationship because the kids aren’t his wives and therefore “bastards” (WTF?!) In a nutshell he has to live multiple lives. He goes sees his parents (without me or his two daughters from the ex girlfriend.) Sees his 2 daughters (from the ex girlfriend without me). Comes and sees me. So it feels like he’s compartmentalized his life. And I told him I don’t want that. What do you guys think? Try and work it out or move on?

After that text exchange. Or as some have called “degradation” he stopped responding to me. Only after I sent him an I love you text (14 hours later) did he respond with a picture of us at a recent dodger game and then a sad face. This is what makes it hard to move on. Because he does things like this that make me want to hold him.
