I'm I reading into this too much?

I have be dating my boyfriend since July 2013 and living with him since December 2013. We both have children by other people and our kids don't live with us. My boyfriends ex just let him see his boys for the first in 6 months time last night ! I was so happy for him because he has done nothing wrong to not see them. But in the past few times he has tried to see his kids, his ex said he could not see them unless he had sex with her. He never did. But when he went to see his kids last night his ex was asking a lot about money and why he couldn't give her any. We have two cars and a house we are buying... Money is tight! But when he was telling her about why he couldn't give her money , he told her that I pay for the cars because they r in my name. I really don't like that. We both pay for our things... I see the cars and the house as OURS. Not His and Hers! And why does she need to know about who pays for what or how much money we make? And now she is trying to get him to do little shit for her that I don't want him to do but I feel like I can't say anything to him because he wants to see his kids. Things like drive to her house to get money from her so he can go buy breakfast for her and the kids.... Although I don't totally disagree with him doing this.... I don't want it to turn in to her riding in our car. And I feel like the little favors he dos for her is wrong to me. I have a hard enough time getting him to do things for me but he can drop what he's doing for her? In all honesty I really love this man... More than I have ever loved anyone... My feelings have gotten stronger recently and now with this baby momma drama I feel that I'm putting a wall up.... Am I crazy?

His ex has a no contact order against him... But it's kind of a mess because they have both broken it... So he does have rights to his children but he is scared that if he trys to get some type of visiting set up that she will turn him in for breaking the no contact order. So it's not that he doesn't have a back bone.. he's just afraid to piss her off...
