So....is it right to leave the person your in a relationship with and expect them not to date anyone for a while? And if they do date someone else not long after you two break up to hate them for it and believe everything that person ever said to you about how they loved you was a lie...?

Basically here is what happened.

-Mate left me
-I go out and do things to get my mind off of it, other wise i would have broken down
-Don't think about it and i start to feel happier
-3 days pass
-Go Larping
-Girl I've liked for 3 years is there
-She says she had been wanting to get together for months and months but i was taken
-She asks me out, I say yes
-Next day at school everyone hates me
-Apparently there is a period of time when im not allowed to date anyone or be happy.
-I can't just move on because that is my only way of coping.....
