I just can't take it any more 
My husband is totally emotionally unavailable to me and the dcs, and nobody is happy. Every day he comes home and straight away tells the kids to go upstairs so he can get some peace. There is no interaction, just "go to your room" 
If I'm not in the room and the baby starts crying, he ignores her and carries on watching TV or playing games.
He doesn't seem to have any respect for anyone, he treats me like the maid, just there to cook and clean for him- I feel invisible.
Our son is being diagnosed with ASD, H refuses to accept that he is not a normal little boy and says that he's "just a little shit" and that I pander to it (I don't- I just pick my battles and as long as he's safe and happy then a bit of odd behaviour is neither here nor there).
Basically I need him to leave, but I want to get myself together first so I don't have to try and do it while dealing with the inevitable fallout.
I need advice- what should I be doing?
