Wow, Adinva, I'm more than a little horrified at your financial situation. It doesn't seem to me like your H is stepping up the way he should be. You sacrificed your earnings for your family - I did, too - and now it's time for him to recognize that. Don't be afraid to ask for what you need.
I also agree with you about the kids aging out. In my state, child support ends at 18, which for two of my kids means October before they graduate in May. It's not right that I should have to support them alone the rest of the time. I know I wont' have to in my case, but, geez, your H needs to man up for his kids here. I hope that works out for you.
I have used Mint (the one MB suggested) for years and years. I check it every day and classify transactions for my budget categories. When the forensic accountant asks me what I've spent my money on for the past year, I have it already.
