he still wants to be at the birth :/ me being as stupid and in love as I am is thinking maybe if he sees me bring our daughter into the world he will come back and realise what a mistake he has made
Your life isn't a Hollywood movie and this isn't going to happen.
If you allow him to be present at the birth he'll have a grandstand view of your intimate bits and he'll then swan off off to toast the new arrival with his ow, with whom he's no doubt already planning to have more dc, while you are left crying over your newborn.
Scrape what's left of your self-respect off the floor and start getting goddam angry. As his equally unfeeling family (apples don't fall far from trees) have told you "he's moved on" and you're best advised to follow through with what you said to him in the restaurant.
If he wants to see ds he can do so on days when he's NOT working as your son deserves to have quality time with his df and not be palmed off to other family members.
He doesn't get to be present at the birth of dd, nor does he get to go with you to the Registry Office for his name to be put on her birth certificate. If he wants to see her it will be at your convenience i.e at a time and place of your choosing. Please note that not naming him on the birth cert won't prevent you from claiming maintenance for her.
Not being married to this utter scumbag gives you an advantage. From now on you call the shots and don't demean yourself by begging for crumbs from his table. Fwiw, a man who believes he 'can't have a life because he has no money' is unlikely to shell out on court fees in order to have contact with his dc and the chances are he'll become an absentee parent once he realises that you mean business and he doesn't get to pick and choose when he has ds.
You'll make a much better life for you and your dc without this unprincipled piece of gobshite in it and I have no doubt that in time you will come to realise that you are better off without him.
Concentrate on your family and support your dm as much as you can. These
are for her with my sincere best wishes for a successful outcome from her treatment. And this
is for you to enjoy after your dd's birth with those who genuinely care for you keeping you company throughout an unstressful labour.
PS If you can take the couches I suggest you do so and donate them to Oxfam if you don't want them
