Do you guys have any tips for rekindling an 'old flame?' No huge falling out or fight. We were casually meeting up for a while last year. We both got involved with other people and haven't talked for a while. I think we're both single now. I had a lot of fun with her and I know she liked me back, how should I go about getting her interested again?

It's not exactly my style to be extremely forward or aggressive which doesn't help my case, I know. For reference I'm 22 she's 21. I'd like to hear your experiences with this type of situation. Thanks boys
