After 3 Years Of Marriage

Way back at about our third year of marriage I find out she really likes big dicks.
Started with dirty talk and questions about a guy that has a big cock that’s a friend.
We all partied back then and he was over a good bit. Apparently he showed her his dick, she asked to see it. Long story short I passed out on the couch and everyone had left except him. She said she was only going to blow him but once he was hard she really wanted it. She didn’t tell me for years, his dick is so much bigger than mine, I was crushed. She said they got together after that a dozen or more times.
She had no problem telling me he was far better due to his size.
She goes though menopause and then doesn’t want sex and gets mad and lays that on me. I felt so worthless.
