Search Results: going slow

Me & my girlfriend have been having problems every two weeks for the whole summer. Last week we decided to take a road trip to Seattle. We took her car since mine is in the shop. The trip was going good until this morning. This morning on the way driving back an oil truck swerved in front of me. I got scared and hit the brakes, we launched forward. The guy in the truck was at fault, but she didn’t see that because she was on her phone. She lost her temper at me and yelled “WHAT THE FUCK IS WRONG WITH YOU? You’re such a bad driver!”. I explained to her why it wasn’t my fault and that she should apologize. She refused to apologize and cancelled the rest of our plans. We had plans to do a photo shoot on lake Washington for memories.

We were running late for the photo shoot because she wanted to stop at a restaurant. I told her since last night we’re not gonna make the photo shoot on time due to the busy long weekend, and so said so done. Then she starts blaming me that she didn’t have to do her hair n make up. She even blamed us being late on me driving slow. I was doing 5 miles under the speed limit because I was driving and looking a my gps when I was wasn’t sure of where I am. Once I got things in order I was going over the limit.

I said let’s forget this fight happened and continue with our plans. She said “no” and told me I’m selfish. And that she’s not taking pictures because they’re not gonna be good memories. I told her “we never have good memories”. She said “then why are you with me?”. I told her I don’t know. I drove her car back to my house grabbed my stuff and that was the last time I heard from her. Should I bother trying to get her back? Or just let her go?

Situation: She claims to be very shy.
Guy shows clearer interest by trying to set up a date in a few weeks due to her being on a long vacation. She shows enthusiasm after 48 hours of no response. She does apologize for it and gives a reason. Guy brushes it off like it's no big deal because it is nbd but honestly just curious why this happens.
Now, she's literally messaging the same way with long messages and emojis, just at a slow pace, every 12-24 hours when it used to be 1-5 hours.
