My girlfriend recently broke up with me. Yeah, it sucks, but the thing is I have been hot for one of her friends ever since we started going out. During our relationship, she and her friend had a huge arguement and stopped speaking to each other. I want to get in contact with this other girl now that I am single again. How should I go about doing this? Should I send her an instant message, e-mail her, or just go by her work and tell her how I feel?
