Please help!

I know how আপনি feel =/ this guy that I used to like flirted with loads of girls even after he ব্যক্ত he loved me, and it made me so jealous that i scared myself!I started to hate the girls he flirted with...but I should have hated him. I also found out that he had a gf, and that he was just stringing me along....he still tries talking to me but i refuse to socialise with a bastard like him.
Jealousy can be one of the most unpleasant feelings ever,not only do আপনি feel guilty with yourself for feeling this way but also আপনি feel that আপনি can't tell anyone because they will think badly of আপনি :S but hang in there :)
Eventually আপনি will forget about him, and someone will come along who is perfect for you! So there is no need to be upset :D also আপনি shouldn't worry about being popular! I used to worry about it all the time (back when i was in school :L )but honestly, just forget about it and do what আপনি want to do, you'll be much happier.
So, my উপদেশ to আপনি would be to সরানো on, start up some new hobbies, meet new people and, should আপনি find someone else that আপনি like...tell them! Because we only get one life and its a fucking short one, so আপনি may aswell give everything you've got to make it a good one!
I wish আপনি luck :)
