Me and Ex T had a lot of misunderstandings. A lot of struggles and difficulties. Right from the beginning all the way to the end. But I learnt from it. I learnt a lot from it, and like with you she never got defensive. Not that she showed me anyway. I think learning how to work things through is good for you. Learning how to fall out, and repair the relationship is important I think. Elio said it all better than me, but yes, it was common in my therapy.
