Well, usually, I'll check my phone as well until I get bored then if she keep infinitely browsing on her phone I just do activities that I like by myself or I go to the restaurant with someone else. I hope this won't change when I'll get married, even if it has to break up the relationship. At some time, she has to know a little bit about data leaks, mass control by the GAFAM, ACAB, open source, linux, or I don't waste more time with her.
It's also what attracts them, she has to adapt if she wants to be the one ;)
