<human>: Been with my 21 year old girlfriend for about 9 months. So my girlfriend had met this guy in Vegas before we met and they had made out. We have been dating for nine months and she still texts this guy. He lives across the country and she said it was just like a penpal thing. 

The amount of texting bugged me but I can be overly jealous. Last night she gave me her phone and I wanted to assure myself that I had nothing to worry about. She had previously said that I could read the messages but I tried not to. I couldn't resist in. I found text messages that were flirtatious and sexually suggestive. 

I called her out on it and apparently she had slept with him when we had said we were not seeing anyone else but before we were official or anything like that. She said the text messages meant nothing and I believe her that nothing has happened since that time besides the text messages. 

Our relationship was great before this (both of us have said this) and she has been very sorry and hysterical. Besides this action, I felt like I was in the best relationship ever. But I keep rereading the text messages in my head. She wants another chance. Am I completely weak for thinking about giving her another chance. If I get back with her how should I go about it.

Can you give me a shortened version of the text?
<bot>: Girlfriend sent sexually suggestive messages to a guy who she had slept with when we were exclusive but not official. I am thinking of staying with her.
