My partner and I have been together for 15 years, while I had a fair amount of experience at university I was his first. Whist I know this lack of experience has sometimes been an unspoken bone of contention I've mostly kept quiet about my sexual past.
About a week ago while having a few drinks with my partner I happened to talk about dating and mentioned the few dates I had been on shortly after meeting him. He got all cold and quiet, I explained that it was before we had become "exclusive" and once we had become a couple I had stopped and haven't been with anyone else since.
He has remained quite cold with me I simply don't understand why he is so hurt by something that occurred when we had only gone on a few dates.
I'm trying to be understanding but I really don't understand.
