So wise mumnetters please tell me AIBU to be a little cautious about her motives, DH thinks I am.
DH GF from many moons ago (nearly 20 years) has friend requested him, I have no issue with exes being friends on FB or anywhere else for that matter, but this has come out of the blue. They have had no contact in all these years, no mutual friends etc so why now! It wasn't a serious relationship I don't believe, but they did have sex.
I think DH should ignore/delete the request, he thinks there is no harm in accepting it.
