While there are women out there that do lie to themselves.
A lot of men do not go up to women and say things like : "I want to get to know you and have a f*ck buddy." "I only want sex and I don't find you up to standard to have a serious relationship with you, but you are good enought to sleep with" They don't say, "I am talking to multiple women and I also want to casually talk to you and have sex with you." They dont say I'm not ready to be in a relationship any time
What I'm getting at is in that thread men want women to be honest up front and even blunt about what they think when they are approached but don't apply the same thing when they are approaching women. Even if it leads down a path that is more damaging then just saying getting a no if they ask for a number. It's in the OP bolded. My point is people are doing things to avoid reactions they don't want. It's about being realistic.
