I absolutely hate it when someone asks us if we're upset about something that would clearly upset anyone. When I was 12 myexboyfriend asked me if I would be ok with him getting back with his ex, and I said ok, and God, that was a million years ago, and to this day Istill regret saying "It's ok" when what I really wanted to say was if you really want to be with her instead of me, then how I feel about it shouldn't matter. I mean, what are you supposed to say in that situation? It's such a loaded question, and shame on him for putting you in this situation. I agree with the above post, call him up and tell him you weren't exactly honest when you said you were ok with it. That it hurts, but you want him to be happy because you love him, and if she makes him happy, you don't want to stand in his way, no matter how much it hurts you.
