Both. Two wrongs don't make a right, it was indeed completely insensitive for him to do that, he should've kept that to himself or in a perfect world he wouldn't have even noticed. For you to give a guy your phone number makes you just as bad as him and even a little worse since it was for revenge purposes. Right now you do not have the luxury to be mad since you did something too. The best thing you can do is move forward and avoid thinking about it.
