I hope you can explain to your new bf that THAT isn't acceptable behavior. If he wants you to "do" something, he needs to ask you, not force you. That's only being considerate of another human! If he can't handle it, then look for still another boyfriend. I hope you have someone with which to discuss the troubling incident. Do you feel like you need to apologize to the other girl? Do you inwardly want to make sure you didn't traumatize her?
