Hey all, I've read most of the sidebar books and am currently in a long term relationship with a woman for the last 3 years.

We have some real good sex sometimes, but it seems every few weeks the excuses happen again. Tonight, she was starfish so I got off her and said "it doesn't seem like your in the mood", and I said I'm going to sleep. She made a few more excuses, and I just said cool, goodnight.

Is there a good way to handle this at bed time? During the day I can just leave, but what about night? Perhaps I said the wrong stuff and looked like a beta as well?

Edit: I played it cool and didn't get upset
