It's all because of DS.
DS is two and awaiting an assessment for autism. This will take time, but we should hear within the next few weeks. The support has been very good.
In a nutshell, DH told me last night that he's 'done' with DS. He said he's a nasty, horrible little boy. He's told me he can't keep doing this, he's ruined so many aspects of his life, and that he thinks 'it's a good idea for him to take a step back, for the best' 
Amongst other things, I said how about how everything has impacted me? I never get to take a step back and I wouldn't, because he's our son and he comes first. He said "Why do you always make it about you?"
DS does a lot of 'different' things that other 2 year olds wouldn't do, I grant you, but my biggest miff is that actually, a lot of what he's doing that annoys DH IS normal.
For example, DS is completely non verbal. It needs investigation and that's fine. He will not socialise or interact with other people, also not very normal. Also does repetitive stuff, does not play or use imaginative play, just shacks items, also not entirely normal.
But, DH seems to start saying and moaning "This is not normal" when it is perfectly normal for 2, just annoying. For example, he woke up this morning and got the heaviest item he could find and started banging it on the dressing table. That's normal to me, although annoying.
DS will occasionally (otherwise eats everything in sight), refuse a dinner. DH will moan "There's something seriously wrong, he's not normal".
DS will try and climb on the toilet seat to see what's in the bathroom sink. DH will moan he's not normal.
Everything remotely frustrating seems to be met with 'he's got serious issues, he's not normal'.
Another example is DS has always slept through, never woken up. Last night he decided to wake at 12 at night, DH was going mad saying this isn't normal. When In fact it's normal, just annoying.
I'm so fed up of all this bollocks, from DH, not DS. The constant whinging that it's all too much, that it isn't fair, that he isn't normal.
Even if he isn't normal, or does have a diagnostic issue, so what?! He's our son. Deal with it like I have to. I can't just 'take a step back' and neither would I.
He also constantly compares DS to his brothers boys. Of whom he hardly knows, and I see regularly. I can guarantee you that both of them do things much worse than DS, just being 'kids', but no, DH swears blend that could never be.
We always see him off to work and hugs him a kiss. I made a point of going down myself to see him off. He did give me a kiss but refused DS
Then said he had to go. Wouldn't even acknowledge him this morning.
What on Earth do we do?
I'm even more angry because he won't reach out and research things for himself, or bother to talk to anyone else. He seems to have his own 'it's not normal' alarm set by himself.
