It’s so stressful, holds no bitcoin , super financially invested in her veterinary practice, and I love that. But oh my god do we argue
Stop it then.
She has her world.
You have yours.
Focus on what you share.
She isn't trying to make you a vet. You won't make her a bitcoiner.
Compromise on one thing. Set up a wallet for her veterinary practice to allow small transactions. And then shut up about it. Let her see people use it, and she might get it.
We offen reject things from those we love because we have biases against a partners "thing".
Bitcoin isn't worth sacrificing your love for her.
Bitcoin wont fix this.
