Let it go - you broke up months ago.
It's done. I was hoping for reconciliation, but that's done. I hadn't been happy for a while before we broke up. There is also no fixing any of that, even aside from her working two jobs and caring for her dad, while her daughter goes to her bf's every night of the week. Her BF and her staying there one night a week, after my ex feeds her dad dinner and he goes to bed at 9:30 or 10, it's just too much to ask for.
My grandma lived with my folks and so did my uncle, including when he was dying. I can't even imagine telling my folks I can't ever stay home for the night with my girl to keep an eye on them, so my folks could get out for the night together.
