... I don't understand.. anyone?

I’ve seen my ex today.. after and exam.. the person I was talking to started talking to him so I had to talk to him to not look impolite.. I miss him so much.. He asked me about my exam and I said it went well and I asked about his, he told me it was good and now they were going to a goodbye party for a friend of his. He asked me how I was and I’ve told him I was going to the hospital because I’ve been having some problems with my hand. He held my hand (grr) and told me if I wanted him to come with me… i’ve said I dunno, if you want to.. you can come.. and he told me that better not because he had the farewell thing… but after the consult to tell him what the doc said.. I mean… what the hell? why did he offered himself to come to then tell me he couldn’t? and I didn’t tell him anything and I can bet that he won’t ask me either… but knowing all this.. it still hurts me and I’m sure I’ll get disappointed at the end of the day when I see the no messages sign from him. He doesn’t really care for me?… I don’t understand.. (it was the 1st time i’ve seen him since over a month)
