Your girlfriend is the asshole here.

My girlfriend says she doesn’t like that I don’t work and don’t do anything to “develop myself”.

Yet, she herself doesn’t work and she relies on you financially.

she says she doesn’t want to get a job because I don’t have one

That’s just an excuse for her not to get a job.

I would get where she’s coming from if she has a job and doesn’t rely on you financially. Sorry but she sounds like a leech that’s complaining her provider isn’t providing enough.

I don’t think you understand what I’m saying. You can set your phone to block all phone calls from anyone not from your contact list. I’ve never received any spam calls for years.

You can just block unknown calls on your phone.
