And it wasn't the first time. He has been saying this on and off for years, in between periods of normality.
He is moody, he shouts and the children for the most petty things and sulks regularly. But sometimes he can "put it all to one side" and behave like a good, loving husband and father.
He says he's not about to leave. Part of me wishes he would just go and sort himself out, because I cannot carry on with him like this. But the rest of me is terrified.
