Should I be worried about her ex? Or am I just paranoid?
My girlfriend and I have been together for over a year. It's been pretty clear that her ex has never really gotten over her. The two have been on friendly terms for a while, but recently they've been talking and texting each other increasingly often. I don't want to dictate who she can and can't be friends with, but I'm afraid of losing her. Legitimate concerns, or paranoia?
