Welcome back ladies and gentlemen of the internet. Love triangles are inherently messy. Being between two different people can get hectic and uncomfortable. When you're in the midst of a divorce, it's better to just rip the Band-Aid off, instead of prolonging it for too many months, or even years. You're only going to end up sabotaging your chances with someone else if you can't make the mature decisions with your current partner, who you shouldn't be with.

As much as this man says they're not together, it's still just a strange red flag to keep up the relationship after all this time, even if it's just living together. His gauche decision to bring over his new girlfriend comes out of nowhere, and the wife isn't too keen on it. You'll have to read the full story below for all the juicy details.
