Well I'm going through a real rough break up and he was my first love. There's nothing that really helps me out besides surrounding yourself with people that love you. That might sound like it won't work but if these people make you laugh and happy, then you'll be able to forget him for that little bit of time.
As far as songs go:
I love the video to Mad - Neyo. It's absolutely great
I also like Moving Mountains - Usher
It's over - Jesse Mc.
Twisted - Keith Sweat
I hope all goes well for you!
