I'll try to keep it short as I it just happened.
Kids got dropped off by their dad earlier. All has appeared to be fine, DP in a good mood as we all were. He went off to cook his dinner (kids eaten and I didn't want anything). DS and DD(6 and on the spectrum/ADHD) asked if they could have a fizzy drink and I said yes, go ask DP for cups as he is in the kitchen. They asked nicely but DP brought out two squashes. (To note, they only have one glass of fizzy a day as agreed with my ExH so hadn't been drinking fizzy all day every day).
That's fine, said to the kids to drink at least half of them then tip them away. DS drinks all of his and I manage to actually convince DD to drink 3/4 of hers which is an achievement in itself. I then ask her to tip what's left away and I will pour her a fizzy drink.
DP stopped her in the kitchen and asked why there was some left. I called through and said I had said they can drink half and tip the rest out. He kept questioning her so I said, again that I had said it was ok. He swore, snatched the cup from her, tipped it in the sink and threw it at her. Obviously she was terrified and burst into tears.
Was in a it of disbelief and asked him if he really just threw a cup at my daughter. He yelled at me that it wasn't AT her, it was NEAR her. I just walked away to go and console her.
He doesn't have form for this at all. He has rarely even yelled, never mind anything else, even when he is stressed. He has now stormed off out and I have zero clue where he is. I'm in complete shock. I was in an abusive relationship before this and it has triggered a panic attack and I can't calm down.
Need some perspective and to know whether or not I am overreacting by being absolutely livid with him.
