Oh. 
Right my love, get yourself into gear. Put your emotions in a jar for a few days, you need to get practical.
First thing tomorrow, get yourself some legal representation. You'll get a free half hour with most places. Make a list of everything that you want to happen, what's been said between you, keep any texts that he sends, log any calls.
Get your passport, all important docs, DCs birth cert etc.... all in one place so you know where they are. Can you take stuff like that to your mums?
Incase he starts playing funny buggers and locks you out?
I take it that he is NOT up for this? I'm guessing that actually he's really hurt so that's why he's digging his heels in?
You need to keep it calm and tranquil for your DC. One year old is nothing in the grand scheme of things and actually, I admire you for getting out if you don't love him and aren't happy.
IMO - better than staying in a loveless relationship.
Be brave, get your head together and talk to your friends/family for support. Let them help you.
You can do this in the right way, even if he protests. xx
