When to give up, how long?

It's been four years and 2 separations since DDAy. I left and got depressed and came back after the last 5 month one. When does a person know it's time to stop trying. H. thinks that I am being spiteful and refusing to move on and it's all 'ancient history now'. Is he right? Am I at fault? I don't mention it much at all but the triggers still make me so sad.
