single at 6 months ?

Has anyone here been through a really bad break up at 6 months pregnant? If so how did you move forward? And do you have any advice because I think I'm heading in that direction. the father of my child is a great guy and very responsible and I love him to death but for whatever reason we just can't get it together to save our lives and I love him so much but I just don't know what else to do.. I've been through a lot in my life and he says that I'm letting it get in the way of me growing but at the same time he's seeing progress, ladies I try and I even go to therapy to get over things that has Happened to me as a child, I believe I'm a great person and I try I just feel like he's stuck in his ways and he's been spoiled his whole life so we just can't see eye to eye... maybe it's me... maybe I'm seeing something he doesnt see I'm honestly just tired and I'm at a place in life where I just want to be happy with or without people, I just don't want to be stressed.. I really can't see what the issue is and I ask is he just trying to find a way out and he insists that if he wanted to leave he would have ... am I buggin out or am I just not seeing what he sees ? Are we both just being difficult ? 7 years is not easy to just throw away, what's going on
