So with my wife, when she was my fiance had several such DDJ occasions - eg. made her take the key to her office on sunday to open and check her computer logs as i was convinced she had opened other chat accounts with which she was chatting with her boss etc.
After marriage it all subsided - we lost 2 babies - one abortion and one didnt live beyond the first week. Our marriage weakened on a sexual level but we continue to live together and behave like friends caring and sharing but lost the sexual bond

I started to cheat and have had 5 affairs since. And with each one i suffered huge amounts of DDJ. This was exagerrated by the nature of the realtionship as each one of them had husbands too - but i never had an issue with their husbands but used to imagine them with a 3rd guy (me being the 2nd in her life).
So basically i would be sitting at my home with my wife on the couch - my lover would be at her house with her husband - and i would be spending my time to track her down and get proof she is really with her husband at that time and not with a 3rd guy. Usually the 3rd guy would be my friend becasue we would normally be in same pffice circle and i would imagine that my lover is not only cheating on her hsuabnd with me but cheating on me with this 3rd guy. Would go crazy - install recorders, hire prviate detectives to chase down someone elses wife!!!
I am currently in one of these affairs and doing the same. The truth is in the intial stage my insecurity is a turn on for the girl becasue my image in office is of a very strong mature man so they find it apeasing that this man has becoem a a puppy in front of them and is so scared to lose them - of course as you all know as the DDJ gets worse this feeling changes into fear and disgust and finally the affair is over.
I trust my wife completely - do not accuse her. Even when she dosent pick up her phone the whole night while travelling i would assume her battery is down. But if one of my lovers was not to pick up the phone for 30 minutes I would be in a fit imagining her having a quickie and laughing with her lover that this man is so stupid calling me when he should be with his wife...
I am so screwed up - i cannot tell this to my wife for obvious reasons...HELP!!!!
