I have been with my boyfriend for almost 6 years now. I am 24 and he is 31. We use to have sex all the time sometimes up to five times a day, and nowadays all I am expecting is just maybe once a week and I'm satisfied. He uses the excuses he is too tired or he isn't feeling good etc. I know he isn't cheating on me because we are always together and have our phones out in the open. I just don't get it. I've tried everything to the point I am exhausted. He always tells me I'm beautiful and that he doesn't want anyone else and that he couldn't imagine being with anyone else but deep down it is depressing me horribly to the point I'm worried. I don't want to leave him but at the same time I am too young and have so much life ahead of me to where it is very hard to live with. It makes me feel useless,depressed, and unattractive. We have even tried talking about it and he says he will try to change it and get better but nothing has changed in months. I am to the point of not knowing what to do and any advice would be greatly appreciated.
