We've been dating for almost a year now, everything was great at first. He helped me after a really bad experience and before being my boyfriend he's my best friend. Whenever we started dating, everything was fine we had fun together and we would have sex everyday two to three times a day then it slowly decreased to once a week (on a good week). I don't know maybe it's because he's older and he has way more experience than me, i don't know what to think anymore, he tells me he loves me and he wants to be with me but it doesn't even seem that way anymore. I feel like I'm living with a friend/roommate instead than with the man I love, the person who says he wants to marry me. He seems to really enjoy it whenever we're having sex but once we're done that's it. Before his excuse was that he was tired and stressed out but he's not even working now, I mean he couldn't have a less stressful life, he would always tell me how once our situation changed and he was more relaxed things would go back to the way they were and nothing has changed. Whenever we do it I don't even enjoy it as much anymore because I don't know when he'll actually want to do it again so I hold it for as long as we do it, so I'm not even being satisfied anymore.... What can I do? What should I do?
