Wine

My best friend and I, (we're both shagirtt girls) used to never go a day without seeing each other. About a month ago, we both got really drunk at a party and hooked up like endlessly throughout the night. The next morning it was slightly awkward, but we've been through numerous situations so I figured we'd eventually move past it. But lately she's been avoiding me and being less and less involved in our conversations. I've bent over backwards to get her to talk to me and practically climbed the Himalayas to get her to hang out. What should I do?
