<human>: Ok guys, I don't know if I should be upset, but I am. Here's the story: ok so she has had a new job, and so she and I haven't been able to see each other throughout the summer vacation. We're about five months in, and I really miss not being able to have any time with her during this break, due to her job. 
Today, we had a miracle, as she was able to have a date with me. So we were in the restaurant, and she would occasionally look and pick up her phone. Mind you, I had my phone out of reach, because I didn't want to be bothered by anyone during my only time with my girlfriend. Anyways, she would occasionally read a text all quickly, laugh, and then turn it off. This happened at least a couple times, and each time, it would be the same process. I wasn't too bothered by it, until she said she was "going to the bathroom". She wasn't even there for a minute, and she took her phone with her. So I knew she was answering texts from her friends. This pissed me off, cuz the way she went along with answering her texts was very suspicious. And I also noticed one time I was turned and had to get the bill, she was on her phone yet AGAIN. I was just really annoyed, because I've acknowledged her that she and I would not talk to other people while we are on dates, doing stuff together. So my question is:

Am I overreacting? Am I really just being paranoid about her texting other people?

Thanks for the help Reddit, and sorry for that wall of text.

Give me the gist of the text in a nutshell
<bot>: Gf used her phone a little too much in my opinion during one of our few dates. Idk how to react. I think I'm overreacting.
