There's this guy I was kinda seeing. He seemed like a great guy except for his flakiness. The past few times we've had plans in advance he has flaked out on me last minute with lame excuses. The other times I've tried to act like it didn't bother me and was no big deal. This time I blew up and told him that I don't care for the flaky behavior and to please not make plans with me if he doesn't intend to keep them. I told him that I feel like he's not interested in me because he of his flaky behavior. He got pissed off and now he's not talking to me. I'm usually the nice, sweet girl who tries to be compassionate and understanding, so now of course I feel bad and like an awful person for blowing up. Do you think I overreacted or was justified in calling him out on his flakiness?
