Incident happened a week ago when coworker crashed into my car in the car park of my job. I was still upstairs in work at the time. 

She knew she hit my car but did not come back up to let me know that she did. Instead she thought about it for a full day before telling me over text. 

I didn't see the damage to the car because it was on the passenger side of the car and it was dark leaving work. 

She said she'd pay for it and not go through insurance because her premium would go up. I took a bit of time from work and went and got an estimate. Received the estimate the next day and sent it to her over WhatsApp. She saw the message and did not reply for 7 hours and she replied saying she didn't expect it to be that much (€500) and she'll have to think about how she wants to proceed. 

Forward on to today and each time I try to bring it up she gets pissed and deflects. Now I'm getting pissed off and while the damage is only cosmetic, it's my car that was perfect last week and now looks like I'm a shitty driver. Am I the asshole and should I lay off her and give her more time?
