OK one day pretty much out of nowhere my girlfriend of about 2 1/2 years called for a break. I found out that on that same night she was a party got drunk and had sex with another man. I was willing to forgive her for this and try and build on our relationship. She still wants a break. For the past couple days I've been so emotionally confused I can't eat. When I sleep I dream about me and her. We are only 19 and she wants to see what else is out their. My feeling is that we are meant for each other and I don't want to lose what we have. I have already made the mistake of letting my emotional rollercoaster bother her over and over and over, peeling for her love.( mistake I know). I do still want her back, but does anyone have any advice for me?
