OK but if there's mutual attraction then the highest gifter thing wouldn't be relevant.
I'm kinda curious to know who this person is haha. He sounds like he has a massive ego!
Tbh op in my experience from similar crushes...we fixate on the fantasy idea of this dashing Prince who seems to represent everything we want. We like that he's slightly unobtainable because if we always think of them as a little out of our league and never actually ask them out, we cannot be disappointed.
Because if we actually spent time with them we'd realise they weren't actually that shiny thing we thought.
It's fantasy. Often due to loneliness or having had a string of shitty men in the past.
Added on top of that that he's paying you attention and saying nice things. Who wouldn't be flattered? But you have to remember he has to be nice, it's what pays his bills.
Enjoy it for what it is if you like but... remember it's just fantasy.
Unless you actually want to ask him out. But of course you know that doing so, would likely pop the little bliss bubble you're currently in.
Put rules in place for yourself if you continue chatting. Remember every pound you give him is less money to spend on you and your child.
