<human>: I feel crazy posting here, because I don't understand why I feel this way.

I've been with my boyfriend for about 6 months now, but we were together unofficially for a bit before then. At first, I was crazy about him! He is kind, understanding, loving, and encourages me to do better. He has helped me through work, school and family problems. He makes me want to try harder and pushes me too.

However, lately I just don't feel much. It could just be the honey moon period ending, but I just wanted to know if anyone else has any answers.

The reason I don't feel much is because 1. Lately, I just don't want to have sex with him. And don't get me wrong, he is SO attractive. Handsome, my type, and fit. I still find him attractive! I just don't want to have sex with him? I am now on medication, so maybe this is why?

He can be a little selfish, but that's really his only bad quality I see so far. Ex. I literally pay for everything. Everything. And he has money. I've just started to say I can't afford paying for most stuff, but I don't know why he can't atleast pay for his own stuff. He makes a lot of decisions based off what pleases him, not his friends, family, or me. Him being a mooch is a big turn off for me, as I am the sole provider now.

Summarize the given text in a few sentences.
<bot>: boyfriend can be selfish, which I think makes me resentful. But he has so many good qualities I'm confused why I no longer want to have sex with him or feel very happy.
