Your obsession with trying to understand why something happened to you is what keeps you in a constant loop of overanalysing. You pick apart the situation, the person, the reasons, and then circle back to it again. This is happening because you’re struggling to accept what has actually happened. You’re struggling to sit with the reality that it broke you, that it hurt you, and you’re trying to avoid the feelings that come with that realisation.
friend of mine just told me a guy she was seeing abruptly ended their relationship after spending a perfect day together, and when she asked him why he did that he said “well when you put a dog down you try to give it one last good day”
