<human>: I try to keep this brief, and if I miss anything information that seems necessary please ask.

Last night I found out fiancee of the past 6 years (Im 24 shes 23) was txting and sending pics to another guy.  Mind you this is the third time its happened, but a different guy every time and never turns physical.  After a small argument she packs up some stuff and decided to stay at a friends house for the night because she was going to take him to the airport the next day(hes not the guy she was txting and is gay).

So in the morning she takes her friend to the airport, buys a ticket and boards the plane with him.  I found out later that morning that she would be home in a few days.  So scrambling I start to try to figure out whats going on, I check the phone records, check bank accounts and then I see it she bought a ticket.

Later that day I finally get a hold of her(shes had a layover) and she tells me she doesn't know about us, and needs this time to be by herself (which also includes 2 friends in a place she said she'd never want to go) 

I want to fly out and I can but I feel I shouldn't even though she did say "then why dont you fly out".

I dont really know how to evaluate this situation and would appreciate any advice.  My biggest problem is that I love her, but I'm not sure if I can stay with her.

Also I am not always the most attentive, I understand how someone would want to seek attention elsewhere.  I just wish these feeling would be discussed before actions.

Any advice please, but keep in mind I really dont want to leave her.

Give me a shortened version of the text
