Keep talking about the store and your finances but do some fun activities for your.
Don't give the $$ if you don't want to. I bet a lot of what your going through now is how your R was before your H left. Change things up. Do things differently here. Take back control of the situation.
And try really hard to do things with your child that will make you happy. Start and you may see how much better you'll feel to put it all behind you for a bit. Will rejuvenate you. You need to gas up to keep going. Your H doesn't have the gave right now so go somewhere else and get it so you can keep the journey going. If you know what I mean. Have some fun this weekend without your H. But stop pursuing him for a while.
