Ok, my folks have gone through some rough patches in the last year or so.
There was a big blow-out in April, my Mom had to leave town because she discovered a love letter written by my Dad to another woman. Very out of character for my Dad. This other woman works at the same facility as my Dad. My Dad apologized profusely and begged my Mom back and they decided to stay together, and work things out and have been in marriage counseling since.
Now, my FIL works at the same facility as my Dad and this woman. He was not privy to the events that transpired in April between my parents.
FIL took DH aside and asked how my parents are doing, because my Dad and the OW (same as love letter lady) have become sort of a joke throughout the facility they work at. Because my Dad is constantly trying to switch jobs/shifts to work with this woman, coming into work hours early to hang out with her etc. FIL believes its physical from what hes heard/observed.
Now, I am thoroughly upset.
I also have this info and feel quite burdened by it. DH waited a few days to tell me because he wasn't sure he should but then decided I should know so I wouldn't be caught off guard when the whole thing blows up.
What the heck am I supposed to do? Wait for my Mom to find out some other way? I don't know for sure whats going on, except for what my FIL said and he lacks credibility at times (but since the whole thing that happened in April...) Do I tell my Mother, do I wait it out and mind my own business??
