<human>: Can you give me a shortened version of the text?

I have been with my fiance for 5 years and we got engaged in September.  Over the winter holiday she went home with her family, and slept with her cousin (by marriage) 2 nights in a row.

She was acting weird when I came back in town but she blamed her hormones so I dropped it.  A couple weeks later the guilt got to her and she told me what happened.  

After taking some time apart we have slowly started trying to work things out.  But the pain is still so real to me and I don't know if I will ever be able to trust her again.  Also my perception of her and my expectations for our relationship have changed alot.  I am not sure if the relationship can ever get back to how wonderful it used to be.

I know how badly this has destroyed her she has been a wreck since it happened and I know she wouldnt do it again, but there is still that voice in my head..

We were originally going to move out of the country together when our lease ends in June.  That plan seems off the table right now, and I am in the midst of transitioning my job and can still move out of the country, but not sure if moving to that country without her will make me an emotional wreck while over there.
<bot>: Fiance slept with her cousin, and we have been trying to work on it since January.  Not sure what to do with my life and this relationship.
