Crossroads

I am at a crossroads in my life. I am 27 this year, have my degree, I have been in a defacto relationship for 6 years and we have a beautiful daughter together. My partner is 25 years old. My 'problem' is that I would love to get married or at least engaged sometime soon, but my partner is just not having it. He said he never wants to get married, thinks that if we do, we will most probably break up straight after. Yes, we have had problems in the past, but we have worked through them step by step. I have sacrificed a lot for him. I have put up, and helped him through his anger problems and verbal abuse. I have put up with his family that I know think I am not good enough for him, I supported him when he didn't have a job, and worked full time whilst being heavily pregnant. I sometimes think it could be he just thinks marriage is a burden and I questioned whether or not he actually loves me as much as I love him. I've asked if we could re-locate, just a change of scene and new challenge, but the answer is always 'no', and I think he is stuck in a comfort zone. There is definitely no problems when intimacy is involved, he is all there, but when its other issues there is always an excuse or 'I don't want to to talk about it' response I kind of feel trapped, or emotionally drained. Please someone out there help me out.
