This is very clear.

You have to leave him, actually it was a mistake to fall in love with him when he was already committed. Though its hard to forget someone if you really feel for him ie. love him deeply.

For you, best way to make more friends and find love where you can get same love back. Otherwise, you will only hurt yourself and nothing more. Do not desperately try to get a boyfriend, rather just do your things ie. if you in studies then look over studies or if working then concentrate on work. Just be social and hopefully you will find someone perfect for your soon who will love you back without any conditions as you do .

Good luck .
