When I first got involved with my BF (we are both 23) in June 2015, he was about 165-170 lbs and about 5'7-5'8. Today, he weighs around 210+ lbs. He blames his weight gain on being depressed and his job becoming stressful, which I understand. He would work 60 hours a week or more and 7 days a week.

This is really affecting our relationship. He doesn't enjoy going out and doing fun things anymore, and hates being outside now. Before this we used to go kayaking, hiking, etc. but we haven't in at least a year. It is also heavily affecting our sex life. Ever since the weight gain, he's never in the mood, always "tired", and wants me to do ALL the work. We used to have sex more than 5 times a week now I'm lucky if it's once a month... all he ever wants anymore is for me to give him head, it's like he wants that instead of sex now. I love him and I still think he is so sexy and handsome :( but this makes me feel ugly and unwanted. I feel terrible because a few months ago he told me he looked in the mirror and cried because of how much weight he gained and none of his clothes fit anymore. I know how difficult it is to lose weight, I used to be overweight 9 years ago and was able to lose 50 pounds because I was dedicated enough. I just don't know how else to motivate him, if he doesn't even want to help himself.

He really has tried though. He joined a gym months ago but with his job he was never able to keep up with it and continued to gain more weight. I've tried eating healthy with him, working out with him and going for jogs but he complains and doesn't want to bother. I've never been mean to him about it, I've always been understanding and supportive. It seems he is only ever interested in doing anything anymore if it involves food...someone please help... how can I bring this up to him without hurting his feelings? We are TTC soon and I fear that this may be an issue...

Update: it's not only that it's negatively affecting our relationship, but his health as well. He tells me he can't even walk up the stairs without getting out of breath and sweating, which I've witnessed. He is constantly sweating and telling me how uncomfortable he is physically, he complains even about taking slow walks at the park with me, even when he had shorter work weeks. This never used to be an issue. I am just really worried about him as well as us.
