Sis, always obey the leading of the Holy Spirit, that is number one. There are no set guidelines that supersuede what the Lord Himself leads you to do. Every situation is different, every person is different, and God is a personal God that works individually with all.
When we do not have a solid word of God to stand on concerning a matter, you have to let the Lord lead you in your heart and spirit. Yes, most definitely God intends for your husband to take care of his children, we can be sure of that as God never intends for any child to struggle or any mother to singly struggle in providing for the children. That would not be of God if you are struggling with no support, that would be of the enemy because he wants you to struggle, and this is why we test the spirits. If it is good it is of God, if it is bad..causing hardships, it is of the enemy and he can appear as the angel of light.
If things are going well however, you are not struggling, your children are provided for, then it could be what God has put in your spirit to do. Sometimes God does things a bit differently for a purpose, even if we yet do not see the purpose, and God is the provider during that time He is working out His purpose. As long as you truly feel God was telling you not to file for the support and as long as your children are being provided for and not suffering from the lack of support, if it is a good thing and not a harmful thing to you or them, then go with what you feel you are supposed to be doing in obedience to God. Obedience to the Lord is priority for sure. Just always make sure it is of the Lord, remember good is of God, bad is of the enemy, you have to evaluate the circumstance as to if it is going well or badly for you and the children.
