If so, would it be better to put my money in a Roth IRA or a traditional IRA?

    This morning my girlfriend told me that a guy that she's been friends with for four years, let's call him A.J, has liked her for that entire duration of time, and that she, even when she was with her ex, would go on dates with him and cuddle and hold hands. She said that she does this despite the fact that she has no feelings for him romantically, she just likes being touched by guys. I asked her if his meant our relationships was over and she said she didn't see what the big deal was. I said that if she cuddled, held hands, and went on "dates" with him while she was with me that it would be cheating. Then she said, " I don't see what the problem, given that I'm single now." Ouch, right? Anyways, later on she said we can still date but I just need to let her have the freedom to be with other guys from time to time, but I told her no and that it was over. We are both eighteen years old. I'm so confused and shocked by all this that I can't think rationally, so to everybody out there I ask, am I overreacting to this?
