Allot of what you have said sounds so much like what I have been through.We have been married 26 years currently living together like roommates after a six month seperation and her filing for D then changing her mind we have now been back together almost 2 years.
I have always been very jealous even though she never gave me a reason to be,that jealousy and control finely caused her to say she had enough,felt smothered and then came the ILYBINILWY.
She went to her 25th class reunion for a weekend without me and I of course questioned her about every little detail of what went on and even though I really believe that she did nothing wrong except enjoy herself with old friends,I couldn't let it go,I let my jealous mind create all these worse possible things that could have went on and drove her right out the door. I have no proof of OM,she did go through a time where the cell was never out of her sight and I suspected maybe a EA but I think once again it was be being insecure and jealous.
Since finding this site and started DBing,things got better because I learned to back off of her and focus on GAL.It's funny when I stop pursuing she is allot more talkative and tells me things without me asking.
As of now we still have no physical contact except every now then when she lets me know she wants some and I have no problem taking care if that itch even though it's just sex not making love.
I believe all of this is both WAW together with MLC and I am hanging in there and waiting for her to make it through to the other side.
The jealousy thing will make you and her crazy if you don't get it under control.
