<human>: Can you provide a brief overview of the text?

**I want to know how to stop being a derp dumbass and how much of a dumbass I was.**

I met a girl through mutual friends I made on the east coast during my summer internship.  We had sex and I asked if we could be exclusive. She said yes, but then recanted the next day.

The only stipulation I had when we began our FWB relationships, was that we had to be open when either of us were planning on seeing someone else. 

She would ignore me in public when we were out with mutual friends and as a result became paranoid and clingy. 

Eventually I got mad with her when she started to see someone else while she was fooling around with me. She apologized for her actions and called off our arrangement. 

Currently, I try to be polite in public and talk to her. A female friend told me I was being creepy as I was asking stalkerish questions. The comment was another blow to my ego. 

Since my paranoia started, I would be an ass and "drop" to mutual friends I fucked her.
<bot>: Emotionally messed up, am annoyed/angry/ashamed by the whole mess. I probably come across as crazy.
