My boyfriend has gained weight.

Ok Glow, please don’t rip me apart for this, lol I’m just being honest & need some solid advice =) Soooo, my boyfriend and I got together back in august. Since then, he’s put on some weight. He’s always complaining about how he’s fat now (he isn’t) and I reassure him he’s not. I do tell him if he wants to change something then just do it, and I’ll do it with him cuz I’d like to lose some myself. I’m at wits end because i don’t think he’s fat; however; I’m not as attracted to his new weight. And I have no idea how to deal with this. I don’t want to say anything at all because it’s hurt me feelings if it were the other way around. I love him to death but I’m just less physically attracted to him which is starting to put a strain on our sex life. How do I go about this? Thanks.

*EDITED TO SAY that I am NOT going to just leave my boyfriend over this. Obviously I love and care about him and would like to communicate this concern to him. He started smoking weed a few months ago 5/7 days of the week and has eaten late at night, and he has gained 30 pounds. So no he doesn’t have any health problems!
