Quoting My Widdle:" I'm not looking to share his funds, I really don't care how much he has or whatever as long as he is ... [snip!] ... because this is something I really want that would make me very happy, he'd be a little more willing to help me, that's all. "
You aren't considering his wants and feelings. Everything you have posted is about you and your wants and how he should take care of your bills so you can do what you want and what will make you happy.
Now, don't get me wrong. I am blessed to have this opportunity to be a SAHM. However, it was both our decision not just me saying I want to do this and he has to take care of the bills alone to make me happy.
Think on it a while. Try to find a softer less "selfish" sounding approach and see how it turns out.
