i think tone is very easy to misinterpret or project your own thoughts into online.... what makes you think they don't feel bad? other than your experience with and understanding of your ex as a person..all ppl with bpd manifest symptoms in their own unique way at different levels. just because they don't pour it all out for strangers online doesn't mean they don't to the ppl they've hurt, or that they dont feel it at all. I have never acted out like some ppl with more extreme symptoms and have only hurt a couple of ppl in my life with my words, and i am only now able to look back and not be overwhelmed by feelings of guilt and shame. even tho they forgave, and forgot all about it, and the love is back and vibrant, and they want me around, they understand (which is the best part).. it was painful to me and very hard to express and be vulnerable to ppl i am close to... my mom and dad, my husband.. many save that tone for the ppl they actually hurt and are connected to, because it can be even harder to express deep feelings to strangers. (for some its easier maybe, but thats not been the case from what ive seen) there is absolutely nothing wrong with releasing those emotions too, just because you screw up in life you don't have to walk around with a cross on your back for the rest of your life.. even if you hurt someone and they dont forgive you, if youre actively working on being better and never doing shitty things again, i think that counts as atonement, but we all have our own ways of repenting. if you were mistreated and never got an apology, or never got over it, im sorry. nobody deserves to be abused, even if that person themselves is hurting, but its not up to a bunch of strangers who have different symptoms and situations to work through than your ex to make up for that... just bc you cant sense remorse in a post celebrating freedom doesnt mean they are devoid of it. just means thats the lens youre seeing the post through.
