Hey American Sweetheart,

Point 1: Chill.
Point 2: Hubby dear did get caught once. Doesn't mean that he has to do it again. Maybe he is genuinely busy. Catching up with friends. Having a drink. Playing pool. Driving around.
Point 3: Don't burn your fuse thinking what he is upto. Instead think of innovative ways to make him burn his fuse. make him wish you were here with him with the kids. That way, tables are turned.
Point 4: Qatar is a nutty place. Everything is available here. Doesn't imply anything.
POINT 5: Don't listen to the advices above. Am sure they will feel the same if their spouses or potential spouses are/were caught cheating on them.

So, in simple words: Chill !!!
