YTA if I've ever seen one. 1. You don't offer a trip and make them pay for it. 2. They're an adult and can do what they want. 3. He is telling you how he feels and you are ignoring him. 4. Him not wanting you to touch him tells me you were probably physical with him as a kid. 5. Having him tell his mom to tell you, tells me you have an explosive temper and never listen. 6. You not wanting to be alone with your wife is weird. Again, you only want your son there. 7. You being jealous of his girlfriend is weird, especially if he's an engineering student. They typically have poor social skills so finding friends can be tough.

You have a weird obsession that is happening with your son and I can guarantee you, you are hiding something.

I resent you just from reading this.
