A better question than the cell phone is what OTHER behaviours is he showing that are odd or make you uncomfortable.
there isn't anything really. first of all, we are physically separated - living in the same apartment building (different apartments, different floors). is seeing someone after you've asked for separation considered 'cheating'?
initially during in-house separation, he started watching football at the bars. that lasted maybe 2 weeks and then he started coming home to watch. he would be home every night. then we sold the house, and physically separated. since then, we started playing squash at the same club. he would play on most weeknights (including friday nights). the past week and a half, he hasn't been at the club. he's let himself go by gaining weight (not muscle). and my l recently requested he justify all his claims on his financial statement with proof. i think that got him in a tizzy and he has had to find time to produce all of this proof. again, could be me justifying his actions?
i would go home to change before heading out and i'd see his car in the garage around 6:30 pm. i'd check out his car and there would be gas receipts, food wrappers, etc scattered all over the passenger seat. i'd head out to play squash, come home around 10:30 pm and he'd be at home. i've noticed that his car doesn't move over the weekends. it's like he stays in his apartment all weekend long. i don't have access to any of his other communication devices (ie. computer, home phone). but his cell phone records are pretty clean - plenty of calls to his parents (which makes you think he's having an A with mom and dad!). i haven't noticed whether he has been dressing better or not. i don't run into him that often despite living in the same building.
but he has changed all of his passwords, created new email accounts, etc.
