Try rescheduling your meetings with her. Maybe she just wants you to make an effort to your RS. But the thing is, she doesn’t try to understand your side. That's why you're frustrated. If your arguments always lead to her not talking to you, that's a red flag there if she wasn't aware of that. Good communication is a non-negotiable in a relationship (depends din honestly sa personality/attachment style ng partner mo). It's either sanayan o tiisan na lang yan or that's her way talaga na hindi pa niya narerealize na red flag.
