Leaving aside the age difference between the 2 which I do find eyebrow raising but ultimately none of my business. what bothers me about this is if he was screwing around on Linda with her. Linda seems like she was a really good person and I thought she was really good for bill . The other thing is this girl has daddy issues or something because her other boyfriend was like 70 or something like that. again as long as this is a mutually agreed upon transaction between the 2 of them,fine. not something i could imagine myself doing,but to each his own. I'm pretty sure he knows she's not with him for his good looks and fascinating conversation . rather he's getting sex in exchange for money basically. My problem would be if one party was trying to mislead the other party and again it's still between the 2 of them but it would be a sad situation if that were the case.
