I have been thinking about this all day and I have come to think that believing that one size fits all is actually a bit unhealthy and responsible for a lot of my own dating confusion.
I am quite a confident woman, but if I am texting a man a lot and being quite openly flirtatious then it means I like him a little, but for the men I really like, I become more scared, more as if i am waiting for them to speak first because I lose my confidence a bit. Most people would not believe I was shy at all, but when I really like someone I most definitely pull away and pull back from fear. I don't believe there are not also men who have these little fears and shyness issues too.
I have come to "expect" every man to behave a certain way, to phone a lot, to tell me certain things, to progress quickly and I take this as a sign he is really into me. A part of me thinks all that means is that (a) they are quite confident, (b) you are ticking a lot of boxes and they find you attractive. The actual "into you" part is something they can't possibly know until they unravel who you are over time.
Saying "do all men act into you if they are" is a bit like saying "do all men" do anything. I really don't think they do. I have seen slow burn relationships that work, and lighting fast relationships that work and everything in between and I think letting go of the expectation that every man who is into you will behave a certain way is probably a good idea.
Not everyone shows how much they care and what is going on under the surface -I know I don't.
