I seem to be the odd one out here . . . a boyfriend/girlfriend relationship was based on intimacy potentially leading to a long-term commitment.
Many things which we see as being 'special' with our spouse has been previously shared with someone else . . . why have this potential problem be a possible thorn?
I understand that relationships can turn into friendships but the history is still there.
An old girlfriend was quite upset when she 'found' a photo album featuring many of my ex partners . . . and I did see her point.
I've never asked my wife to discontinue contact with her previous ones and she hasn't asked me to either . . .
It depends on the personality
Did that make any sense?
