Context to the question: My long term friend and I have been going through some tumultuous times in both our lives. We both live in different states. Last year she was extremely suicidal and so I visited her more often. She started guilt tripping me about not taking a vacation with her even though she has a lot of other friends who are emotionally and physically closer to her than me. My hesitation arose from the fact that I'd just broken up and gotten laid off. So after countless sessions of her crying and begging, I ended up taking that vacation with her. We has a good time but I realised that I was thrust in a caregiving role during this trip due to her anxiety. We ended up having an argument once we were back as she believed it was my duty to prioritise her since she was suicidal. I'll spare you the details of the argument, but the catch is that she's always going through something that is worse than my situation.
The request for space: After this argument she told me that she'd need some time before getting back to me and this argument as her life is a messy at the moment. I was happy to take a step back because I was also going through tough times and did not have the energy for this discussion.
Current situation: However, since then she keeps sending me random updates about her miserable life every other day. I am unsure if I am supposed to respond to it since she asked me for space and she clearly is not willing to discuss our argument or take accountability. I feel like she's trying to breadcrumb me in a sense? I am confused, what would you do in this situation? what's the protocol!!?
