I need some advise

Myself and my girlfriend (well ex) split up almost 2 months ago, for reasons on her part. I still love her so much and i dont know what to do. We're still very good friends but it hurts me to be around her, which doesn't help as i work with her, and all of what i feel for her makes it hard to concentrate (either at work or at college). i've even thought bout leaving work. i want to be happy again, but the only way i was happy was when i was with her.

Please can someone, anyone give me some advice?

Thanx Steve G
