Does he want to trick my mother into having sex?! ⇐ General

[Anonymous]

My mother works as a teacher at our school. I have a school friend whom I have known since third grade. About a year ago his parents divorced. As far as I understand, he stayed with his mother, but in September or October last year he asked me to introduce his father to my mother. Well, in general, they came to visit us, sat and talked. That's it. Here. And after that, my friend’s father began to come to us alone. Moreover, a friend says that he rarely sees him, but we see him almost every week. If I'm at my grandma's on the weekend, then when I come home, we always have almost a pizza wrapper with a bottle of wine or champagne in the trash. As I understand it, he wants to trick my mother into sex. Why did he decide to hit on her after the divorce, if he hardly knew her before? How can I stop him? And why did my friend help him meet her?
