Stop doing this, it’s delaying your healing

Stop looking at them objectively,yes they may be the dumper,avoidant, or whatever mental shit they're going through but stop looking at them through those lenses only because you're forgetting that they're a whole human and adult who has made the decision to leave you AND hurt you, they didn't do this only because they're avoidant and hurting or whatever they did it because they wanted to do it, the sooner you stop doing this the faster you will heal.
