Was playing with DD in ex's garden today when I went to pick her up. Ex picked up ball and threw it at me really, really hard. I ignored it and a few minutes later, he hurled ball at my head. DD was faffing with something in the garden and didn't notice. I just said something facetious like 'you really need to let go of that anger, it's not healthy'. He just laughed. We tend to keep a distant relationship (i.e. I only engage with him on matters concerning DD and ignore enquiries into my life/him checking the wall calender 'surreptitiously' every time he picks up/drops off DD). It just seemed that he really did want to hurt me with the ball, which is strange, as he's not like that at all.
