Been dating this girl for about 2 months (she was an acquaintance for 2 years before that)

She's pretty sweet, feminine and submissive until now. Does things for me, talks about marrying me(we're still in our early 20s)

I've been facing some issues with getting a new job, some issues within my family and my recent side hustle failed so I'm pretty bummed out. Still sticking to building things and on my purpose, but there's a sense of dejection in me when it comes to the issues I mentioned.

She notices this usually when my face is a bit upset. She's been asking me "What's wrong", "You can share your problems with me" and other similar questions.

One day she got upset by me not telling her my problems. "Why are we even in a relationship if you can't share your problems with me?"

Personally I don't understand the value it would bring to explain my problems to her. She isn't going to help me solve the issues in my family or help me build my side business.

So I don't see why I should tell her except the emotional "I'm dating her so she should know" reasoning.

Again today she asked me to share what's up with me... I avoided the question as usual.

What's should I do? I know being vulnerable in front of her will dry the pussy up quick. I also don't see the value in sharing my problems with her.

What should be my approach here?
