<human>: Can you condense the text into three sentences or less?

Basically, the other night when she was showing me something on her Twitter she accidentally went to her messages, me being a guy noticed someone messaged her something about boobs and instantly went to "wtf is. That mode" she then hid her phone until I convinced her that I needed to see what these guys were saying. Well come to find out there was 2 guys both asking for nudes and stuff, she didn't send them any to my knowledge but did give her number so I'm not to sure what they talked about from text. One guy however that she was talking to said that he wanted to do it, but was states away and she said come here, and I like it rough, and even flirted about marriage and having his kids. This right here is what devastated me, ( side note these were sent 2 months ago) we have been looking for a house together and also both have said that we want to spend the rest of our lives together, I have always trusted her, but she on the other hand is really controlling and always thinking that I am going to cheat on her, when I don't even text or talk to other girls. So when I found out she is doing the exact thing she thinks I'm doing I am just confused furthermore I am having trouble letting go of this issue and really finding it hard for me to give my trust to her again.
<bot>: found out my girlfriend has been messaging guys on Twitter about having sex, but they are from different states. I am having a hard time letting go and just confused as to why she would do that.
