What's that word?

At least, I think there's a word for it. Basically, what do you call it if you really want something, but once you get it you don't want it anymore?

See, Will's parents are treating me like part of the family now. Which is nice, but I'm kind of mad that they had seven years to decide to treat me right and didn't do it until we got married. Also, they're boring me to tears with the conversations they suck me into on the phone. I don't know these people you're talking about! I don't care! Here, talk to your son.

Obviously, I feel extermely guilty. I mean, I'm annoyed that I'm getting what I wanted? I am such a bitca.
