How to be a single parent?

Hi,
My P of 7 years left yesterday, I told him to go if he meant all the things he said as I couldn't live with someone who didn't respect me as a person. I have a 2yr old DS. I'm just sat here still in shock I guess trying to work out what the hell am I supposed to do now. I am a SAHM so financially I am worried, emotionally how do people cope when they just want to cry but keep a brave face for their children? He hasn't contacted me since not even to see how his son is. How can he shut off his feelings like that?
He told me he only sees me as our sons mother nothing more. We had been arguing on and off like what id imagine any normal couple would with a baby/toddler who never has never slept through a night. fights mainly were about me being annoyed that he was such a slob and i didnt feel I should do EVERYTHING for him, yes I would be happy doing all the childcare and 99% of housework but if he could mange to put his clothes in the laundry basket rather than the floor or wash up a dish after himself once in a while. Maybe I am just a nagging woman , im not even sure. I think he has done a bit of a number on my self esteem and has left me feeling like I should just accept this behavior, should I?
I just cant even believe I stood up for myself like that, I'm really not sure if I should ring and say sorry?
How do people cope with the crushing loneliness ?
Sorry this is a rambling post I am quite confused my thoughts just tumbling out .

Morning all and thanks for your replies . I actually slept all night last night!!
It is early doors so I think I'll focus today on my DS do something fun . Then tomorrow start getting all the financially side in order.
I didn't call him ! So I feel quite proud of myself . I wish he would bloody call though and show he cared but I think he doesn't appreciate me so that won't be happening.

And so you should feel proud of yourself, OP. We all know how hard it can be at this stage, but it is well worth it.

Did you sleep all night because your DS slept all night?
If so, then that is a very telling sign indeed. He feels calmer and happier with him out of the house!

You should get over £500 per month from him for maintenance payments.
Get onto CAB and find out what benefits you will be entitled to.
You may well find you will be just fine.

Well done. Stay out of contact.
The best thing right now is for you to gather family and friends around you.
Get all the love and support you can right now.

And make sure he doesn't shirk his responsibilities as a father.
He can have him for 1 over night every other weekend.
If he does have OW that will scupper their weekends.
It also gives you time to go out and find yourself again.
Don't let him dictate on this.
Of course if you don't want this then don't.

You're doing great - keep going.
