imo don't dwell on or try on this too much. Are you really changing to be less logical/straightforward, or just learning to put on a show? Asking because in the long term, your act will definitely drop if it is not a deep rooted change. The girl might complain that you used to be funny 20 years ago etc.

Also try dating apps, even Tinder. I know 2 couples who ended up being married having met on Tinder. Rare but it happens.

Expand your social circle in anyway. Work, hobbies, dating apps/events.
Know a gamer married couple in a game I play but don't know their story. Likely met in-game as both are damn good players.

Definitely get you. I had difficulty talking to girls and in general up until my early 20s even though went through co-ed schooling life, except final year. Eventually sorta backfired as was too sociable with female colleagues

But it really depends on your partner. I've met introverted and quiet couples. I don't get it but hey it works for them. Maybe they connect on other stuff.
