Who's to Blame?

Even when it is not your fault, you partner blames you for little things and big things in everyday life. They do not care enough about the healthy course your relationship can and should take and so, putting blames on you becomes habitual to them because holding someone else accountable for their own actions is easier to fulfil, is it not?
If they truly cared about you or your relationship, they would take the blame and not the other way around. It is just one of those small things we do in the name of love and friendship.
You two have a fight. One leaves. The other sits there wondering the why and how of it all. You’d expect them to have the decency to come to you and confront you about what happened, to clear things out. Seems like you had a blindfold on; for they never do, just blame you for everything without clearing things first. Maybe you aren’t in a position to; there can be many reasons. But if they really cared about the relationship, wouldn’t they come and sit with you and talk things out? The matter speaks for itself.
