My gf cant make it to 3.0, what now?

Hi, serious question: me

And my gf have been together for about a year now. We met at a tournament during which tome she was 2.7-ish. She is now barely pushing 3 despite me

Offering to pay for coaching, and investing a lot

Of time into helping her improve.

I told her from the jump that pickleball

Is more than just a game to me and she said the same.

A year into our relationship it seems that that was all just for show. Pickleball is what I live for and honestly I feel I’ve been cheated because the skills never followed suit. Because she has now barely made it to 3.0. Meanwhile I struggle to invite her to 4.0 groups because we’d get crushed. Should I continue trying or is it time to move on?
