I'm so sorry you are having to go through the pain of seeing your grandmother in the state she is in. I dealt with that for almost 4-years with my grandfather, and it's so difficult. You remember the woman she used to be, but see what has become of her today....and there is no controlling it. Just remember SHE still needs you, no matter what her state becomes she needs to feel love from her family.
As for your H. Why are you still letting HIM control the situation? He reminds me of a friends H....who constantly complained about the lack of money but would make it impossible for her to work, because every job she found somehow inconvenienced him. What he really wanted was for her to find some way to work from home and be supermom too.
You already know your H is going to bitch no matter what you do Chrissy...so why aren't you doing what it takes to make YOU happy? This is why I say you are still letting him control the situation.....I get this feeling he wants you to feel trapped, and well....your enabling it. Is sitting in a house where you feel trapped making you happy? Doesn't appear that way to me. In fact..I'm thinking if you stayed in bed until 2pm, you are heading for depression (if you aren't already there).
Chrissy...your H is the King of Catch-22's when it comes to you. NOTHING is going to make him happy unless you can manage to somehow become 2-people, one who works and brings in the money, and one whose there for his every whim. He's not that concerned about the kids IMPO, he's concerned about him...he just uses the kids as an excuse.
