My boyfriend and i have been together for about three years now. For the first two and a half years we had sex very often, but in the past few months his sex drive seems to have almost disappeared. He says he's tired, and that his job is stressful, but I don't understand how he can be tired and stressed every single night. And it's starting to effect our relationship. I've been worried that it's me. I was off work for a year and gained a bit of weight, and I have been trying to lose it, but it not like it's going to happen overnight. Of course he says it's not me, but I still wonder. Sometimes I feel like he doesn't love me anymore.
Is there anything I can do?
