Most Helpful Guy
If you love that guy, all you have to do is wish him luck.
what happened between you two was a friendship and it wasn't really a relationship... I mean, that guy didn't promise you anything by the end of that relationship.
I know you're hurt and I'm sorry, but you have to stop blaming yourself and accept what happened... you were a good friend, so the best thing you can do is wish your best friend luck.
there's a thin line between love and friendship... put both of them in the right place and give yourself a chance to start over.
