Last year uncoverd a mass of deceit and several affairs. It was a complete and utter shock!
Totally out of the blue. I discovered a dodgy single text. A sudden gut instinct told me to look. It was a fleeting moment not something ponderd on before looking.
That dodgy single text made me suspicious. I didnt confront straight away. I decided to snoop. I know not everyone would approve of this but hey - you now know at the very best he has been sneaky behind your back.
What I am trying to say is that initial text I found led me to suspect my hubby may have been having an affair. Never ever did I think I would uncover what I did. Me and my best friend (the only person in RL I ever confided in) agonised over exactly when my hubby, doting Dad and Mr Family man would actually have the time for an affair. What I uncoverd over the follwing few weeks was horrifying. He had been leading a double life and shagging any slut willing to believe his cliched bull shit "My wife does not understand me" etc etc.
Much research on affairs has taught me that few men (and women probably) admit to the full depth of their deceit initially. They go into damage limitation mode. They may admit to flirty txts, even maybe txt sex but deny meeting, then eventually they may admit to just one meeting for a drink "but nothing happend" and so on until eventually bit by bit more and more comes out.
I know for a fact if I had confronted my hubby over that one text he maybe would have admitted to some degree of relationship with that woman but I would never have discoverd the others.
From what you say about the OW slamming the phone down - makes me suspicious. Why is she not trying to make you see nothing has happend between her and your OH?
Use this time to search everywhere. Don't let on you are still ultra suspicious. If he is upto no good he will be being extra careful right now because you have come close to finding out (IF there is anymore to find out).
Search cars, look behind panels, underseats. My OH hid condoms in a flap in the boot for changing the light bulbs in the rear lights. Wardrobes - search all pockets of any clothes. Even stuff he has not worn for years. They may hide that secret sim, mobile etc in a pocket. Look at your home differently. Where would you hide a mobile if you were having an affair. Then look. I know of a lady who discoverd stuff behind the bath panel!! Does your OH spend time in the garage/shed etc - if so when he is out go out and have good poke around.
Also start looking at his behaviour. What does he do when your on the PC or engrossed in the TV etc. Does he get up and leave the room? Where does he go? To check his secret mobile for txt? Don't follow him, dont try and catch him out there and then but listen or try and work out which room he is in. Then when he is in the bath or out - have a good look. I kept a little diary in secret and made notes of where I was and where he said he was etc etc . When I looked back over several weeks - some things didnt add up etc. Make notes of any suspicous numbers or texts your finds. list dates and times. It may not mean anything now but you may find something later that may make it add up.
I hope for your sake - you find nothing because there is nothing to find. But by being clever and little savvy - you may discover if there is anymore to know.
Hope this helps. I am 16 months on an it hurts like hell still. I wouldnt wish this on my worst enemy.
Good luck.
