I am sorry at which the speed of the separation agreement is proceeding and glad at the same time. You will find comfort and peace with the security of the unwanted settlement. I understand the conflict of wanting and not wanting this agreement. Take solace with the knowledge of your limited pressing for this. H pushed for and got what he wanted. I believe someday he will realize it is a lot more than he bargained for.
Regarding SD19, I totally agree with helping her, when you are able to. I would not even ask H about it. You control you. If you want to help then do so, leave him out of it. If SD19 does not feel comfortable talking to her Dad, that’s fine. You should stay out of that relationship. I’ve got between my kids and their Mom, and paid the price.
Besides you should ensure a good relationship with SD19. Her asking you to ask her Dad - I see it as she was actually wanting to ask you (you are the sane and stable parent). Just tell her that. I am sorry you’re short $150, I am willing to loan it to you until payday. This creates your relationship, communication, and trust. Things SD19 needs more than money, and will not likely get from Dad for quite some time.
By the way, cleanly shaven, never wore a beard.

Feelings are fleeting. Be better, not bitter. Love the person, forgive the sin.
