Nope. You know what's a great idea... mixing alcohol with major life decisions. Ends well every time (sarcasm).

If you have come out to her as a cuck and it sounds like you have. You need to implicitly state that you are okay with her fucking other people. Her being safe? You won't really know.

Using a guy to get drinks at the bar? That sounds like some bullshit right there. She should leave her ring on. Tricking dudes into buying a taken woman into buying her drinks is shitty. IF she's wearing her ring, and they know she is married, then great. But she should be honest and upfront.

It's a recipe for disaster. And it is unethical as fuck in terms of behavior. The guy could have been chatting up an available woman instead. But he wasted his night with your wife? Just a dirtbag move man.

If she can't afford to buy her own drinks at the bar, then perhaps you've got bigger fish to fry in your relationship.
