Is it all in my head?: My boyfriend and I have been together for 6½ years. He went on vacation a few months ago without me (I could not get out of work), and he met a woman on the plane ride there. She is his age, had similar interests, and loves beer. He gave her his number with the intent of possibly setting her up with our mutual friend whom he was visiting on vacation. They had all hung out a few different times, and he hung out with her one on one while drinking on vacation. Now normally, I wouldn’t be peeved. But my BF failed to mention her to me the whole time while he was on vacation because he said I would overreact about the whole thing. Fast-forward a week later, and they have been texting nonstop. She came out to our area, which is where her parents live, and my boyfriend made it a big deal that he didn’t want me to meet her. He felt that I had too much hostility toward her, and he didn’t want me to embarrass us. He told me that he does not find her attractive, and it’s simply a friendship. But his sneakiness with it while on vacation is what really bothered me. Why hide it if there’s nothing going on? This would be different if it wasn’t a “new” friend. I have never felt this way with his previous female friends. I have gone to therapy about this, and I feel that his behavior with her is borderline emotional cheating. I’ve confronted him about it, and for the past three months almost every argument is about this person. I understand that we all seek out connections from other people, but please tell me: Am I overreacting? Is this normal?
