Gosh girl....I so hate that for you. This post brought back so many memories for me. What I do NOT understand is why do they bring them in their homes. I mean how STUPID can one be? Do they want the wife to say "ok honey, I like her too and I totally understand why you wanna f*** her, she's awesome!" Geez!
My fathers 1st whore, slept in the same bed with me, the eve of a big beach trip that she and my MOTHER was taking TOGETHER. We stayed up talking about how "perfect" I would be for her ""perfect" son.
Then when my Mother found out, it was heartbreaking. I can remember her BF coming over to comfort her and my Mom would sit at the table and cry and cry and cry. Sad sad.
I'm sorry for you, it sucks but remember this, his role as a father is totally different than that of a husband. I hope that makes sense.
Hang in there and be strong for your Mom!
