My heart got crushed by my ex again. I thought we had a chance of getting back together untilhe got a girlfriend out of the blue over spring break. He still flirted with me, but the day afterward I stopped wearing his sweatshirt, and made myself up to look really nice to show him what he lost. I think he kinda got mad and so attempted to make me jealous by talking about his girlfriend in front of me. It did make me jealous, but I tried not to show it. Today he seems to be avoiding me, but he looks every so often. I'm trying to make myself seem like I don't care, although I do still like him a lot and wish we could be together again. Am I doing the right thing, trying to put out that I don't care that he got a girlfriend and I'm trying not to seem as interested as I was?
