I was thinking the same
@HongKongPhooey. It's a long time to provide a vital piece of evidence. Even if was a passing comment she made to him... what made him think of it a year later?
Just a thought... but if "he" (or another) was aware of all her liasions (because she either spoke to them about her encounters or they were around her when she had a new man at her side), and "he" also had an interest in her and she gave "him" the brush off, how would it make "him" feel? Angry? Rejected? A what's wrong/ why not me feeling? Could "he" have confronted her about it?
