Sex after weight gain?

I've been married for 2 years. I've gained about 40 lbs during that time and now when it comes to sex I feel like my husband just doesn't want me anymore. He expects me to rub him off every night, but when it comes to me there is no foreplay from him whatsoever and the few times he does try, he's way too rough and just gives up when I say it hurts. He also doesn't believe in lube so penetration is extremely difficult. However, he will play with my breasts to no end which I hate, and I've told him there are other things he can play with. I want to have fun in the bedroom, but I'm tired of giving and never receiving. What do I do?
