I thought of that but he swears that isnt an issue (not that I am completely convinced.) I will say that there are no other signs of cheating. Of course, if he has had a one night stand somewhere, I would have no way of finding out. His bizarre behavior would make a little more sense if it was guilt. I can say that I seriously doubt there is someone steady. First of all, we share a family plan cell phone (which he has made no effort to change) and I get detailed billing (which he has no clue about.) He works out of a truck all day so his cell phone is his only means of communication. I went through 3 months of cell phone records without so much as 1 unknown phone number. Secondly, he often calls me on his way home and when he gets to his mother's house, calls me again from the house phone. It does make me wonder if he has had a one nighter somewhere and is ridden with quilt. I wish he would just be honest if that is the case.
