Help! New to this...still hoping for R

[Rusty]

The money thing keeps getting in the way of my DBing and I'm not sure how to handle it. Right now, because I am unemployed (looking and doing some projects until I find something), my H is giving me enough money to cover all of my and the kids living expenses. Due to wedding expenses (S-24), HS graduation (S-18), D's birthday, and S-22 needing some extra money, I have been really running short and starting to fall behind in some of my bills. I periodically ask H for more money each week and it is becoming almost every week. Yesterday I asked him for more due to the above expenses and he said (which he has said before) -well we need to talk about this. I always say - "I'm happy to talk about this if you have some sort of solution to talk about because I don't have one until I find a job". He always gets mad and just says "I can't keep doing this" to which I simply say "yes you can". I know if is kind of flip, but he is paying himself enough at "our" company to cover what he gives me plus some for him and my dad almost completely financed this venture - so I don't feel he has any right to try to cut me out. I try not to get angry, and I have done pretty well, but my last line is always a bit snippy.
I also feel angry and frustrated that we would have no money issues if we were still living together.
I called him back after about an hour and told him how I felt about the situation, that I feel worthless and unwanted because I can't find a job and also by him. That I was trying but I couldn't force someone to hire me. He said he understood, and that "whether we are together or not" we have always been good a finding solutions and he wanted to talk with me about alot of things when he gets back from the HS reunion. Said he had a reason for wanting to go and it wasn't what I thought (hooking up), but for confronting some of his childhood issues. (??)
What are your thoughts about this conversation and how should I handle this convo on Sunday?
