I think a) I am overreacting and b) this post should carry an alert for being dull.
Married 15 years, 2 DS, 12 and 16, very happy despite little in the way of physical affection these days - but this is consensual. We spend a lot of time together (think walks, coffees, and some of our work overlaps as we are in the same industry).
His first proper love was X, and she left him. When we first started dating, what seems like a billion years ago, he mentioned that she was his first love, he had a song that reminded him of her, all ok as it fitted with the conversations we were having at the time.
We both left other people to start our relationship (he had moved on from X at this point and so was leaving Y), and I was expected to cut off all contact with previous lovers - understandably as I had had three on the go (one of which was my now DH) and so was not a beacon of loyalty.
When DH and I got together, X (first love who broke him etc) was still in his life as a friend, had started her own family, and he was still very friendly with her parents. We went round to the parents a few times, and then I woke up and wondered why DH was allowed to keep this ex-lover friendship alive when I had let go of mine - who were all bloody good company.
So I asked him not to contact her any more - no biggie as they were just twice-yearly texts, and by this point we hadn’t seen her family for years. He agreed.
Last night a saw a text from her on DH’s phone. A new text thread started, I assume because he had deleted the old one at my request (so he would have remembered my request because the text area would have been empty). Innocent “How are you” stuff. He had responded. Then, a couple of weeks later, a text from DH to her wishing her a happy birthday.
AIBU to feel pissed off at this?
