Same, no social media for me, never had one account on anything. But, you have to understand how important it is, and then decide the cost/benefit. Here's some game:
what she wants to do with you is
1) bond through the shared connections on social media
2) look at your profile/updates/stories and gauge the parts of your life she wants to engage with
3) eventually she will like your posts, and you like hers, and you establish that synergy
4) then eventually, one of you, probably you, hits her in the DM, or a text and you either meet up in some common place or go on a date.
There's a few instances I shared where super bad like bottle girls gave me their number, but what they wanted was the social media. and I don't have it. so sometimes you lost out on that, but with most people, it's an expected part of the process.
the last thing is, all this, to me, creates more and more distance between two people actually being physically intimate, and this is where I think a lot of that trend of people having less sex comes from.
