<human>: My GF has worked 3000 km away 4 months of the year for the last two years.  One week before returning at the end of this summer she broke down crying during a skype date and said that she had sex twice during the summer with a co-worker(once in June and once in August).  She has been back home since Friday (we live about an hour away from but see each other every weekend).  

She is truly sorry for what she did and wants to do anything she can to make things work between us.  She blames her infidelity on losing sight of  the "big" picture during the summer as well as letting the distance get the best of her.  I'm looking for advice as to what losing sight of the big picture and letting the distance get to you even means. please help reddit.
