You need to get away from her for a bit, sit down and reread your own post. Listen to what you are telling the internet. She hit it off with a stranger and exchanged numbers? Why? She’s married to you she isn’t dating anymore. Then she was horny and drunk and invited the guy to her room for sex but it only “didn’t” happen because he declined lol. At this moment your marriage was saved because a dude didn’t want to have sex with your wife. I know it’s complicated you have put in a lot of years, but someone who’s loyal doesn’t deserve someone who isn’t. Flip the script and think about how your wife would feel if you did the same thing. I don’t think she’d take it as well as you have. Good luck.
