I slept with this guy, he used me..?

He told you he had feelings for you so he can get laid. You feel used because you were used. Learn from this because any guy who cares about you is not gonna have with you if you have been drinking. He would keep you company and talk to you if he sees you've had one to many but he wouldn't take advantage of that situation knowing you were not in your right mind. Quit texting him and let him think. Your acting like a bug a boo which is what girls do in this situation. It scares him off but that's only if he really had feelings for you in the first place. See me personally i would be more worried about my reputation then the man but then again that's just me. It hurts but just learn from this and give him some space. Don't make eye contact just do you and act like it doesn't bother you and keep a smile. If he tries to start a convo cut it short unless you see he is gonna answer your question. Any other convo cut it short. This works. Its called acting your hurt inside but you never show a man that he has that kind of power over you or the relationship will never work even if their is one their.
