I love him and have been with him on and off for two years now and I have kids and they love him and he loves them. But he has a kid with someone else and feels that he has to be with her because of that and he says he would be happy to be with me for the rest of his life but feels like he needs to be with her. She has left him 3 times now and just takes off for no reason and can back this time for the kid. He says he loves both of us. He well always have a love for the morther of his kid just like I do for my kids dad. His big deal is he dose not want a broken family but now days you look a round and they are everywhere. He is happy with me and we do not fight like he dose with her. We all live under one roof now and fight to spend time with him but the more I sit back and let her do her thing the more he tells me he loves me and all that what do I do he makes me happy and I make him happy is OK to bring his broken family and mine broken family together and she finds her only place?

You mean his ex lives with you? No wonder he does what he does. I don't think he, or her will change this living arrangement. Maybe you should though.
