Can't sleep am so angry right now!!

So apparently, in the extremely vague and hostile conversation that has been had by text message, him leaving is my fault and he accepts no responsibility for what's happened!! Unbelievable! He has given no real explanation other than using the things I have said to him during him leaving and since he has gone, plus it being a bad thing that my son came first...what mother would do anything else? I have apparently shown my true colours by 'shouting the odds' at him and shown him that his decision to leave was the right one through my behaviour....you have got to be kidding me?! Was I supposed to have been complicit in him leaving and helped him pack, held the door open and waved good bye? What wife, particularly a pregnant one, wouldn't have tried to stop their husband leaving by threatening anything that came to mind? I refuse to let him make me feel responsible for what has happened. If he wasn't happy, you talk, you don't run away. I'm not a mind reader. How can anything be resolved through silence? If a person wants input on something or has an opinion, they should open their mouth and say so instead of accusing things being all one way. If one of us didn't have an opinion, nothing would ever have been done around here. The anger I feel is stopping me sleeping and all I have is a very bad taste in my mouth. No matter the situation as he thought in his head, walking out on his unborn child is unforgivable
