My bridesmaid has been with her boyfriend around 18 months. I already thought he wasn't right for her as his mental health problems was making her anxiety worse. However, he recently crashed her car (they shared driving it but it was her car) while driving too fast writing the car off and because he was driving without insurance, even though he lied and told her he was insured to drive it, he ran off from the scene and initially told her that the car had been stolen, before admitting that he actually was the one driving.
Her family told him he has to buy her a new car but she's still waiting for that to happen, and it's been 2 months.
I now just don't like him and I have no idea why she's still with him. I also don't want someone reckless like that at our wedding.
Am I being reasonable by not allowing him to come to our wedding?
