<human>: We'd been broken up for ~4 weeks after dating for ~9 months and I hooked up with another girl during this break. I get back together with my girlfriend, she asked if anything happened and I said no because she's put me down for all my past exes by saying I have "sh*t tastes" and that they're all ugly. This hurt my self esteem and since it happened during I figured it wasn't important to tell her. We're together for a month and her friend texts her saying the girl I hooked up with was his cousin. She finds out and FLIPS OUT, comes to my house and dumps everything I've given her onto my bed, sprays pepper spray on it and tries throwing gatorade on my clothes.... She wants to take a break and says she's "single" but I "can't go on dates or talk to anyone" to prove to her she can trust me. I hated it but gave it a try. That was on Monday, then on Tuesday she goes to a friend's house, blacks out and hooks up with some random guy. She also had a few guys ask her out and she didn't go on dates with anyone but had told them maybe and then canceled at the last minute.

I feel *awful* about what she did. Placing me in some weird power prison and then hooking up with a guy. Yeah we *technically* single but I feel sick to my stomach that she did that ONE DAY after saying she "had no intention of going on a date". I get she's mad at me for ruining the trust, but I now have anxiety about that situation and just think she doesn't care about me. She said she was 99% sure she wanted to be single and wanted nothing to do with me and that's why she did it, but I'm sick of dealing with this pain I feel because of it... Am I being unreasonable?

Summarize the given text in a few sentences.
<bot>: Lied to gf about a hookup I had while we weren't dating, she wants us to take a break because of the ruined trust and hooks up with a guy the very next day. I feel awful.
