I’ve been meeting up with my ex and talking things through but the other day we got into an argument. He recently had knee surgery and had metal plates in and has crutches to help get around. We were sat in my car and were arguing over something and I was staying calm but he loses his temper quickly. All of a sudden he banged his crutches into my windscreen and it caused quite a bad crack down the passenger side. I do have insurance that covers my windscreen but my excess is around £80 for this that I have to pay for a full new windscreen as it reduces my visibility and wouldn’t be legal to drive around with it like that. He’s refusing to pay or help towards this cost. Basically just told me on a text no won’t be paying. Aibu to think he should? I’m just so upset that this has happened.
