I didnt ask her but i assume  it was because  she didnt want to verify  yo her x husband that we were having an affair behind his back.

Anyway she has moved on 2 months after we split and i assume she is happy now , i have to start accepting this now simple as that

Probly uncomfortable  cause she just left her marriage  and i dunno i am 44 and she is 32 and it wasnt a argument  just a disagreement but i felt i was good enough to sleep with  on the sly but not good enough  to be shown in public
