I was in my boyfriends so called "junk" drawer grabbing something he asked me to get and I saw a card upside down in there. Was seeing if it was the card I had given him and it turned out to be a card from his last gf. He says he didn't know it was in there but I'm still uneasy about why he still has things from his past relationships. Just bugs me. Am I over reacting and should I just forget about it?
