My friends convinced me to go to a bar with them and, long story short, they pushed drunken me to go to first base with this girl. I felt like s*** and confessed to my fiancée in the morning. She wanted time apart so I’ve been staying at my sister’s for a week. Now I find out my best friend, the one who pushed me the hardest, is trying to persuade my fiancée to leave me. He’s been asking to take her to “cheer up” dinners and bought her “feel better” roses. Did my BEST friend seriously try to destroy my relationship to get with my fiancée? I’m barely stopping myself from kicking his a**. We both liked her in high school but I thought he was over it.
