Me and my boyfriend are currently living together. I have found that I have become comfortable in the relationship and gone up a couple of dress sizes in the time we have been together and he has also put on alot of weight. However, his weight is affecting our sex life as he can't seem to function correctly and we haven't had sex in months as he has no drive to. I am also increasingly concerned about him having potential health issues and whilst I've raised my concern in a supportive way and encouraged change he is reluctant to eat healthier, stop drinking and hasn't yet started to exercise despite keep saying he will go to the gym. I have began being active myself in order to be healthier and I would love for him to join me but he won't and there is always an excuse. I love him so much and he is great in other ways but I'm only 27 and I don't know what to do. I am very much thinking towards my future, children etc but am worried I am waiting for a day that may not come.
