I had a similar situation with WW asking for stuff from the apartment months after leaving. It was never much and it stopped soon enough, but my plan was to tell her: "OK, you do one last round and then it's over."
It is important that you take care of yourself because it will make you better for everyone else. That's what I learnt in therapy and some reading. It seems to be a lesson I hear over and over: "Love yourself enough to be kind to yourself".
You've felt responsible for your parents, MrFantastic, your kids, your boss, etc. You are a Nice Girl. You feel guilty when you take care of yourself as if it's an act of selfishness. Hopefully, you will not see the opposition between making yourself happy and taking care of your kids, no more than you see the opposition between sleeping and taking care of them. You need one to do the other.
This New Guy seems to bring you a lot, to make you feel good and happy. It looks like a nice source of energy and motivation for you. Something to be excited about and that will put the antics of Mr Fantastic into perspective. Carve a little space for yourself: everyone will be grateful.
