I am so sorry you had to go through that. We cannot let people like this bring us down, they are losers who doesnt deserve anything we have to offer. It is his loss, because you are a great person you know? A dare? He is just a childish idiot and I am so sorry he hurt you like that. It must, because he also betrayed that sweet person he portrayed in himself. He was very wrong to hurt you like that. Anybody would feel down, and I know that it won't be easy, but you need to keep confident. Be glad that you found out the jerk he was so young too, and it didn't develop into a long term relationship where the hurt would have been way worse. Belive in yourself, and remember how much he missed out on :)
