Got drunk and messed around with a friend?

your friend was curious then and her inhibitions were low, but now that it's a new day she's thinking "straight" again. It's tough to be friends with someone you wave feelings for, and you definitely complicated your situation by fooling around with each other. You're going to have to have a talk about it, but it doesn't have to be a talk driven by your unrequited feelings. You should probably just explain to her what happened, and tell her you you mixed your romantic feelings with the feelings you have for her as a friend. It's easy to cross the line, and you shouldn't be ashamed. But you need to talk to her and let her know that you don't want your friendship to suffer over one night when you crossed a line you both didn't even know you wanted to cross.
