sex and relationships

Kelsey
I've been with my boyfriend for six months now. In the beginning we would have sex all the time. But then winter hit and my depression (I have SAD which is a seasonal depression) really kicked in and I just didn't want it as much. I didn't think it'd be a big deal but I guess it is for him. He wants to have sex at least twice a week and I'm willing to having it twice a month. I have to talk myself into it most of the time. I love him to death and we are very compatible. I feel like when it warms up I'll be wanting sex a lot more but I can't get him to understand that. I just don't know what to do and last night was really bad. He brought up the fact that maybe we should just be friends and I just don't know what to do to fix it.
