So a friend of mine is currently over in Afghanistan as a civilian contractor. Him and his wife (I hooked them up) moved out to Colorado for the job. She doesn't really know too many people and its hard on her when he's gone for other trips, especially now since he will be gone for 6 months (left two weeks ago). She says she tries to stay busy and it does help. During a recent conversation with her, she mentioned a friend of hers is coming out to go snowboarding. He was staying for free with the cousin of a friend near the resort and was going to buy her dinner before he flew home. Recently things changed for this guy and that free lodging is no longer available. She said due to costs, he may have to cancel the trip. She offered to let him stay at her place. She has a past with this guy. They used to be in a relationship and were also friends with benefits. She says that the marriage is great and Shane (my friend) is a wonderful husband. She confided in me that she "often wonders how her life could be different" and "if he is really the right guy for her". I thought at first they got married too quickly, but never said anything because all I had heard was how happy they were making a life in Colorado. For all I know, he could just be staying in a spare bedroom or on a couch and won't even be around that much. Should I drop my friend an email and let him know whats up? Should I try to talk to her and find out what she's thinking? Or is it none of my business and I should just stay out?
