My boyfriend and I have been dating for about ten and a half months. Not long for most, but for us it’s been a while since we’re both in high school. He just now told me that there was “someone else” just before we started dating and he took her on one date on valentines day, just a few days before we made it official. He said he liked her but he liked me more so he ended up dating me, and to top that off he still hangs out with her regularly, and never invites me. Should I be mad about this? I mean, he did wait 10 1/2 months to tell me this….
