Is it me or am I about to have a nervous breakdown

I am 30 weeks pregnant and have been with my partner on and off for four years. The main reasons we break up are because of the people he hangs around with 98% of the time. They all smoke weed including himself and all i have wanted since expecting is for him to spend more time with me and to stop smoking. I'm stuck because he always chooses them over me and im trying so hard to get him to want to spend time with me that i think im loosing my mind! I actually feel like im going crazy. I know your all gonna think 'leave him' but im stuck cos i love him so much that i can't be without him. We row so much cos he feels he does enough for me, and i feel it's not enough. I feel so depressed and on the verdge of a nervous breakdown. I don;t know if it's cos im crazy or he just makes me feel like im loosing it?????

First of all, I'm sorry girl! *huggs* ...

The problem seems to be that he takes you for granted, his priorities seem to don't include you, and that is not good, since your in a relationship TOGETHER....and you can't keep pushing yourself to force him to be with you, just breath, and try to relax, you need to understand that he's the problem, you can't change him, he doesn't want to be changed. I know that "leave him" sounds temptaing, but no, I can't tell you to leave him, because you can't do it alone, what you need is suppourt. Get together with people that care about you, and that will probably help you to get through it :) ...try to stop depending so much on him, him loving you, him making you feel better, try to think about your baby too. It's a hard decision, that only you can take, but if it helps, there is a lot of people that cares about u. So be strong, and try to take the best decision for him, you and the baby!
