Most Helpful Guy
Yes it is awkward. I say leave it alone. Because he seems to disappear on you. And it seems like when you text and meet up with him that it turns into a sex thing. You can text him if you want to see what he says. It depends on how he feels about you. I say concentrate on the new guy your dating and leave the ex alone for a while.

Are you wanting to get back together with him? Or was it just a stupid mistake that you tend to only make when you are drunk? If you want to break up with guy you are currently dating, and get back together with your ex, text him. Just ask him if there is a chance that the two of you might get back together. Then at least you will know.
If it was just a drunken mistake, apologize to him, delete his number and old messages from your phone, and next time you go out drinking, give your phone to a friend to hold for the night.
