Messing with my head!

Today I had an unexpected message from.... my ex. Yup, that's right, I haven't talked to him in about a month and a half and after our last conversation, I haven't wanted to talk to nor hear from him. So today while I was at work I was logged on to MSN Messenger, like usual, and I was working at the copier for a while. When I went back to my computer there was a message from him. First he wrote my whole name out and then he said something like "just wanted to say hi.... hope you have a nice day". WTF!!! Why would he feel the need to even say that? Doesn't he realize that by even saying anything at all he is bringing hurt and angry feelings back to the surface of my mind? When I saw his message I felt a mixture of fury and the strong desire to start balling. Luckily I was able to compose myself, since I was at work and all. What is wrong with men? Are all men so selfish that they have to act on their feelings and completely disregard ours? Or is it just this stupid man in particular?
