Most Helpful Guy
There was one thing you said that revealed what I think was going on. Nobody gets out of a relationship, gets over that person, and then manages to find somebody else all in the span of two days. If a guy goes through all of that in such a short amount of time, it means that the girl was already there, and you just didn't know it. I'm not saying he was cheating on you or anything, I just think that he saw another girl that he wanted and started thinking with the wrong head. This is in no way your fault. As far as your sarcastic attitude goes, that's not something you should really worry about. Sarcasm can sometimes help a relationship when used in the right context. If it's joking sarcasm, that's a good thing. However, if by sarcastic attitude you meant always coming off as being angry at something, then that's bad sarcasm, and that is something you need to work on.
