Ok, here's the deal......there's a good chance I'll see my ex at a mutual friend's bday party on saturday. We were together over 7 years, she jumped ship in march and no more than a month later moved in with her current bf. Needless to say, she broke up with me over the phone because she is a weak person, so really there was no closure. I'm even waiting for some of my stuff back. How do I handle this situation? Do I try to ignore her for the sake of starting drama? Do I say anything at all? If so, just a simple "hi"? I really need to be prepared because it was kind of a tough hit. Help?
