Sadly some people will never our grow that mindset or the mindset that just because someone is nice to them or hangs out with them, that means they want to sleep with them or owe them things.
This is silly. It's one thing occasionally hanging out with your male friend and another thing to go on vacation with him and his family and wearing his initials etc. Your friendship with a guy isn't as intimate as Lisa's with Fred. Also I can guarantee you, if you made a move on him, he wouldn't say no. Because at the end of the day, he's a man.
