I’m giving you unsolicited advice. Stop befriending men who are the same age as your father. Stop ignoring and or encouraging creepy grooming behavior.
I was a naive 17 year old but a 50 year old saying he wants to “lay me across his lap and spank” would not have been responded to. Well neither would being gifted money for as of yet divulged reasons.
I would have placed him on full ignore. You respond to him in ways that make it sound like you are okay with his behavior. It’s gross. You manipulated him as much as he manipulated you. The difference being he’s an adult and you are not.
stop manipulating creeps because you will eventually manipulate the wrong one and quite likely end up harmed by it. This dude is a stupid gaslighting creep but you will find adept gaslighting creeps who do it so well you don’t even realize it.
Preserve your youth for as long as you can. Avoid adult conversations with old men.
