I too used to be one of the “nice guys” you are absolutely right. Women SAY they want that... but thats NOT who they choose...
when they are young and stupid it’s true, but most wise up by their early to mid 20’s.
“nice guy” is code for annoying. Non “nice” guys aren’t mean, they just aren’t begging for attention or appearing at the girl’s beck and call, so they are attracted to them. Most “nice” guys are just annoying schleps who the girl doesn’t want to be with.
So you’re not a nice guy anymore?
