Big Hugs for you, wonderwhy.
dont't think you are worse than a maid. A maid takes care of children for MONEY, you did that bcos of LOVE. It's totally different.
Your hubby is not playing his part in the household matters except for bringing in money. If I were you, I would find the correct time to talk to him about this nicely, hopefully, not crying. Yes, he is tired from a whole day's work, but if you cant manage with all (as you have gastic probs too), you have to tell your hubby. Discuss this problem together. Let him know that you aren't trying to give him more probs, but hope to solve this together with him.
Try talking to him and let us know how issit after which.
GOD BLESS, dear.
