There was a really good post made here a few days ago in response to a never-been-kissed FA fellow. The response covered a lot of MGTOW protips that can be found here, I wanted to link it but I couldn't find it, so instead let me highlight one of his points for those other forever alone lurkers among us.

That girl you liked, that you were super nice too and thought she liked you but then you asked her out and she rejected you?

STOP TRYING TO FIGURE OUT WHY SHE SAID NO.

Just stop. It could have been for any number of reasons. Women do things for their own reasons, reasons people on this sub will be happy to tell you about at length. That is not what this post is about.

This post is about:

STOP TRYING TO FIGURE OUT WHY SHE SAID NO.

It's not healthy. You'll drive yourself nuts. You are probably fine, probably have some flaws like we all do, probably not Brad Pitt, none of us are, but trying to pin it on one aspect, your car, your height, your odor is a complete waste of time.

That isn't to say ignore self improvement. Self-care is a big part of MGTOW. Eat right, exercise, read good books, make healthy choices. But do it for YOU, not for her or anybody else.

TL,DR: STOP TRYING TO FIGURE OUT WHY SHE SAID NO.
