Some pointers I've learned:

When messaging a girl, use rhetorical ambiguity. Don't ask her if she believes in "love." Substitute in "hugs." Be true to your feelings, don't lie to her, but as Sun Tzu would say, never corner your opponent, leave her with options to interpret your statements.

Once you've agreed to hang out already, you can tap it down a little bit (unless she's initiating), and just tailor your messages so as to remind her you exist.

Also get into an active hobby like parkour, or cliff diving, etc. That way when she asks you what you're doing, you don't just say "nm, u?" You actually have a plausibly interesting thing that you could be doing.

I try way too hard and come across as needy.

I ask for validation a lot.

I care too much about the opinions of people I talk to.

People generally see through the games I play: going back and forthe, trying to be coy one moment then spitting out I love you the next. Basically, I make an ass of myself and people call me out for it.

I alienate friends in group settings (I included group txt convos too).

It makes me really unattractive.

I don't demostrate much high value and I'm not very good to people around me - something I need to work on. I have to allow people to be good to me, and be good to myself too.

I ignore people's indications of interest, and I show little self confidence. There is often interest on both sides on my social encounters, but I execute all wrong.
