So, my girlfriend (20f) and I (22m) have been together for a little over 10 months now. We haven't had any heated arguments or fights, except for the fact that she keeps tickling me randomly despite the fact that I've repeatedly told her to never do it again because I can act strangely to it (something from my childhood which I won't delve into).

Now to get to the current situation: this week I've had my car returned from a paint job and some major look changes and I was really satisfied with the results, so I took a day off from work and took my girlfriend on a short trip outside the city. We drove to a lake, ate some food and relaxed for a couple of hours until it got pretty dark and we decided to head back home to get some sleep as I had to go to work the next day and she had an exam. On the way home, I started talking about how happy I felt with how the paint job turned out and out of nowhere, she starts tickling me. I pushed her hand away and told her to stop, then she reached for my ribs with both hands and got me swerving off the road.

Thankfully, nobody was hurt (although my car got some deep scratches but that doesn't even matter anymore), as I already slowed down after her first attempt to tickle me. I'll admit that I told her "what the fuck is wrong with you" as soon as we stepped out of the car and she started crying, but I couldn't care less as I felt as if my veins were about to pop.
When we got home, I told her to pack her things and go to her best friend, but she threw a tantrum and begged me to forgive her for "a little mistake".

I didn't say a word, I simply stared in disgust and pointed to her luggage. After her friend picked her up, I tried to go to sleep but my mind was racing, so i barely got any rest. This happened on tuesday, and she's been blowing up my phone ever since, but I haven't answered any calls or texts and just blocked her. This led to her friend coming to my house and telling me to at least hear my girlfriend out, but I've told her to fuck off and leave me alone, which made her tell me that I'm more in love with a car than with my girlfriend.

So, AITAH in this situation? Should I talk to my girlfriend? I already feel like I can't trust her after what happened and that our relationship can't be fixed.
