My girlfriend [26F] is displaying some concerning behavior.
I'm in need of some serious relationship advice. My girlfriend [26F] and I [29M] have been together for just over a year now. Generally, things have been going quite well, aside from a few typical minor disagreements that most couples experience. However, we did have a significant argument early on about her past relationships, particularly one with a guy I'll refer to as John. Before we started dating, she had been texting both of us simultaneously and meeting up with him without either of us knowing. Though it was challenging, I managed to forgive her since we weren’t officially in a relationship then; we were merely getting to know each other. Now, I’m facing a new concern. She plans to visit her family next month, and I discovered she was messaging an ex-boyfriend she dated for a short time about three years ago. Their conversation seemed casual—just catching up and chatting about life. The issue arises from the fact that she suggested they meet up while she's back in town. While I feel secure in our relationship, this situation is raising some red flags for me due to our earlier complications. Additionally, I noticed that after initially seeing her texts, they later disappeared into her deleted messages, which felt like an attempt to conceal something. We have an open phone policy, so I wasn’t invading her privacy; I just couldn’t help but notice. She hasn’t mentioned any plans to meet this guy, yet it strikes me as odd that she wouldn't discuss it with me since she was the one who proposed hanging out. I'm hesitant to bring this up with her because I don't want to come across as insecure or overprotective if it turns out to be a non-issue. Nevertheless, it’s weighing heavily on my mind. I could really use some advice on how to navigate this situation. No one wants to be betrayed, and I’m worried that could be happening again. What should I do?
