Been together 7 years. Both 60s, retired, children grown, grandchildren (him). We spend about 4 nights a week together, but have our own homes and neither of us wants to live together permanently or marry. We hang out, we travel quite a lot, get on great. It works for us.
Last Sunday we'd had a lovely day, cooked together, had quite a few drinks, and started chatting about exes.
His ex before me was 20 years younger. They were together about 18 months but she ended it because she wanted to get married and he didn't. He said "The sex was amazing ".
I can't get this out of my head. It's all I can think about, even though my rational side accepts that we all have pasts at our age. He can't understand why I'm so upset - doesn't think saying this is a big deal.
AIBU? How do I get past this?
