So for context my wife and I have a good group of friends and in that group we know someone named 'Liz' (hiding real name for her privacy). She's 35 and was married for almost 5 years but divorced her husband on account of infidelity on his part.

She's always been very timid and reserved. It's not the worst thing in the world but since the divorce she really seems to love attention from men. She's been seeing this guy for a bit and he seems nice. We were having a birthday party for one of our mutual friends so my wife and I invite Liz and her new boyfriend.

He doesn't show up but she does. She says he's working. Which was kind of weird this is at 8 PM and the guy works at a bank. So it's just odd I know there's always a chance but it threw me off. Also at the party was 'Brad' (also not real name). He's been single now for 5ish years and I can tell he's very anxious. He's been taken advantage of by various women because he tends to commit and overlook some really bad traits.

So at the party Liz starts talking to Brad and Brad gets infatuated with her. He's letting her drink his beer, he's grabbing her food, he's head over heels for her and this is an hour in to them meeting. I take Liz aside and ask her to not lead Brad on. I know how he is and can see that it's not going to end well. Well she snaps at me and storms out. Brad follows. Then a few others leave.

Wife's now mad at me for 'ruining the party' but in my opinion it was lose-lose either she was gonna lead him on and that comes crashing down or I bring it up and stop the awkward train wreck but deal with the fallout.

What do you all think? AITA? Could I have handled this better?
