Hey, did you ever follow up on this?

Iāve been on and off the forums and donāt know if I missed it
Oh no! Lol. I forgot all about it due to finals. (shudder).
Itās all about the history for this story. My sister dated a guy who was nice at the time, but I guess he had the 20 year old onset of mental illness situation. (dry sarcastic voice here). Anyways, he strayed from his Catholic roots, began drinking and treating her badly, so she broke it off.
Fast forward a year laterā¦he secretly gets around her and starts dating one of her friends (the friend had never met him, see how sneaky this was?). Anyways, he engages this women very publicly, at which point sister and friend find out what happened. After about 6 months of engagement, he breaks it off, very publicly. Then comes the confession: he had been pretending to be Catholic and chaste and was essentially sleeping around during the engagement.
My sister and her friend stayed close friends and got away from him, fast! This happened just over the summer, so it was very recent.
Well, MIL is close friends with the family so you are all gasping right now seeing where this is going. She told him to RSVP directly to her and approved his uninvited date. Not only did he show up, he brought along the girl with whom he was committing adultery during his engagement. Besides that, this was a formal celebration with a stiff headcount. Security told him no. He was outside the door for an hour with his date, as all our guests were coming in!!!
My sister and friend were nothing short of terrified as this person wasnāt just a jerk but abusive as well. They literally hid in the bathroom. My dad attempted a polite request for him to leave which he completely ignored. But this was something I didnāt take into account: the bride and groom are BUSY during the reception! I literally got dragged away to do things. The next thing I know he and his date had snuck/run in. Security said they couldnāt physically remove anyone due to liability, so our options were 1) leave him be or 2) call the police into our reception!!!
Anyways, thatās the crowning horror story of the day, lol. Everything else was simply splendid.
