Do you think the relationship is the most important things in you live? if yes, sorry, i dont know how to help you. if not, then there must exist something you want to realize,like ur dream. Please love urself more. Only you love urslef firstly, will others love you. Dont get depressed, i am sure ur friends must care for you much. So spend more time on ur friends. Also, this guy is not a good one for you. Even he couldnt get rid of his last relationship, how will he can get together with you. He is a man of not being responsibility. Forget him. You dont need to waste time on this kind of guy.

Hi ,you'll feel sad for a while. Go out with your girlfriends, buy some new clothes & make up. Say to yourself: I am beautiful and worthy of love every night before you go to sleep.

Make more friends and you will find friendship is so important in your lives at this moment. Guess there are many people here who you can make friends with. Time will heal all wounds. Hope you recover well and soon... Cheers

Focus on something else and start a new relationship.
