There’s a difference between ‘faking’ / trying to become something you’re not and improving your communication style /skills. You’re meeting women, not flirting, and not progressing into the kinds of relationships you want. You don’t need to start ‘flirting’ (whatever that means to you), but maybe you can change what’s happening after meeting people. I assume your speaking with people you find attractive? How do you build a connection with them? How are you letting them know you’re interested in taking things further?

There’s a big difference from A) meeting women, being pleasant, and hoping that one of them asks you out, and B) meeting women, having some friendly conversations, then asking if they want to start dating. Those are extremes, but the space in the middle can all be considered forms of flirting.

Flirting doesnt need to be some special way of making eye contact, or lame pick up lines. Having fun, making jokes and being silly can be flirting. Asking someone politely if they’d like to get coffee some time can be flirting. Flirting is just the process of letting the other person know that you’re interested in them in a romantic / sexual way, and good flirting is letting them know that in a way that doesn’t make them uncomfortable and makes it easy for them to respond without making things awkward for either of you.
