I've recently ended a 4 year long serious relationship, I'm not posting anything online whatsoever, not meeting up with friends as much as usual. I keep myself busy with work. Basically my ex hardly know that I'm still alive. Keeps posting photos and hanging out like nothing happened. Our relationship is doomed actually but I feel bitter that she's so much indifferent. Am I bad for wanting her to miss me and grief over our relationship even shortly?
