<human>: It's been over 2 months since I broke up with my ex.  Three weeks before we broke up, she went on a trip to Wyoming with her friend.  Afterwards her behavior completely changed, and I noticed she added a new facebook friend from Wyoming that was exactly her type.  I didn't want to bring up the guy since I would have sounded like the cliche jealous possessive boyfriend so I just let it be.  It was a combination of possible shenanigans with this guy and her increasingly ignoring me which led me to end it.  I didn't bring up the guy because I figured I was better off not knowing.  

I found out via facebook that 2 weeks after we broke up she flew across the country to see this guy.  This will sound dumb but it really got to me that over 1.5 years there was zero evidence of our relationship on facebook, but on her first trip out there she's posting about it.  That was the point where I called her and and asked her to come pick up the rest of her stuff from my place and exchange keys so that we could officially part ways for good.  I brought up all of this for the first time when she was over to collect everything I missed during the initial breakup.  She insisted that nothing happened while we were still together.  I've tried to make peace with the fact that I'll never know what happened and when.

1. Does it sound reasonable that things were totally innocent when we were still together?  It would be nice to get a second opinion on it since I don't feel comfortable talking about it with any of my friends yet.

2. I keep expecting to have some kind of closure and to think about it less, but it's still something I think about most days.  Maybe it's because I never got to hear her acknowledge that anything happened?  I dunno.  I really just want to move past it and just let go, but I'm having a hard time doing that.  I know nothing good is coming from me dwelling on it.  How can I go about it?

Can you provide a brief overview of the text?
<bot>: I'm still hung up on possible vine swinging that may have happened at the end of my last relationship, how do I move past it?
