Its really hard to see him as he is in my same college
I had a break 3 months before still I think I lik him and cnt see him with other girl

I don't noe how to get over him... tht too I think he is doing on purpose... he irritates me follow me and try to show me with that girl...

Suggest me ways...

Well I would think in this case to just find another guy. Yes I do understand that you still like him. But if you would just hang out with a different guy at least it will prove to you ex that nothing about the break up is bothering you.
And if he is purposely showing you the new girl he's just a down right . I'm sorry but that's not even right to do.

So u mean to say that I shuld get a new guy and show him the same way he is doing... do u think thts the only way... and if so then whts the difference between him and me... dnt u think its like a revench...
