Thanks for the hugs Bill3 and UnaLuna.
The second to last paragraph of my OP says it all: I need to take care of myself. This individual is starting to consistently show me she has no time or energy for me. Whether I'm imagining what might happen or its intuition, I do not want to find out and at this time, I'm out. I'm done, until I'm stronger.
I think its important to say that.....when she said in a text she felt like she "failed" as a friend, I didn't feel pity or concern for her. I felt...annoyed and like she was being fake. I don't know what that says about me lol, but yeah. Maybe we are not a good fit anymore at this time. We really are not that close. Like there's something lacking. I feel like I don't really know her.
Anyway, this is my choice atm. I need to take care of me.
