One of DH's friends is a charming raconteur, amusing company, bon viveur. He is also thoroughly untrustworthy, has skipped the country (now returned) to avoid debts, his family have disowned him, he has been made bankrupt and has been sacked (mostly for dishonesty of one form or another) from every job he managed to talk himself into. He lies routinely. He refused to support his daughter, who has no contact with him.
He preys on women, I think, although you forget this when you spend time with him. I've been to two of his weddings (missed the first one),and met numerous of his girlfriends. All of these have supported him financially.
DH views him with tolerance (a) because he is an old university friend and (b) because he is very amusing, but of course we are not particularly close to him.
Now the fourth wedding is on the cards and I've met the new intended, and she is truly lovely. Wealthy of course, hence DH's friend's interest, but totally unworldly. She has no idea what he is really like.
It's horrible though, seeing this lady being totally dazzled. I'm worried he's going to run through a large sum of her money (he has previous and he gets through the folding stuff fast) before she works it out. She probably doesn't even know about the borderline criminal stuff.
It's none of my business of course, and equally there's nothing to be said to her. I'm puzzled how we even know a rogue like this, tbh. But I really can't stomach going to this wedding.
AIBU to plead a prior engagement?
