it is always easiest for the person initiating the breakup.
why? because in coming to the decision to breakup, they have already grieved the relationship, at least in part.
and the person on the receiving end often feels like the rug has been swept under them. often times, they never saw it coming, and theyre left blindsided, confused, hurt, and in search of answers.
knowing this doesnt go very far in taking the edge off of the pain, but it is, in part, by finding those answers that we heal.
She may or may not be fine. It is not something you are going to be able to know because you are not in her head.
i agree with this.
people with bpd traits are especially good at compartmentalizing. certainly, people with bpd can over share, and wear their heart on their sleeve, but publicly grieving is, often times, not something they like to do. my own ex just told stunned friends that our breakup was a long time coming. she wasnt wrong - but she was also just repeating a line shed heard me say about someone else. its not something she really wanted to get into or deal with.
i went down the rabbit hole of seeing my ex appearing to be "fine", and searching for signs that she wasnt. the honest truth is no one really knows, and theres no sense in torturing yourself with a perception of what you cant really know.
