I believe that she is either rewriting marital history (and if so, then you need to find out where she is investing herself emotionally), or she is drawing lines in an effort to stop your sex issue.
If she is not rewriting history, and if she is actually being honest, then you need to be packing up her things and setting them to the curb in an efficient manner today. No reason to live with a liar. Twenty six years is a long time to live with a liar. Time to end it now.
If she is still trying to quell the sex issue, then as I posted to you previously, you need to tell her exactly what your intentions are, and you need to do it today.
Now, changing subjects. Did she have a long term relationship before you?
All the best, -NOPkins-
I will ferret out an affair at any opportunity.
-An affair is the embodiment of entitlement, fueled by resentment and lack of respect. -An infidel will remain unreachable so long as their sense of entitlement exceeds their ability to reason.
