If he only makes $10,000 a year as you say, your support will likely be far lower when set by the court. You may want to check your figures, because that is far less than minimum wage, and he is paying you more than 100% of his salary as you report it.
Regardless of whether he files for legitimization or not, you have a right to file for child support, and you need to sit down with a lawyer, find out what he really makes and determine what is best. Noe that since you chose an illegal relationship rather than marriage, he has not duty to pay your mortgage and utilities and in choosing not to be married, you lost the ability to seek that. But you can seek support regardless, and since I suspect you have been terribly confused by obvious financial misinformation from him, you have all the more reason to see a lawyer ASAP.
If you find this answer helpful, please mark it here on AVVO as helpful. In answering you, I am attempting to communicate general legal information and am not representing you (and am not your lawyer). Do feel free to call me at 404-768-3509 if you wish to discuss actual representation (the phone call also does not retain counsel; that requires an office visit and appropriate paperwork). In that a forum such as this provides me with limited details and doesn't allow me to review details and documents, it is possible that answers here, while meant to be helpful, may in some cases not be complete or accurate, and I highly recommend that you retain legal counsel rather than rely on the answers here. (You can also email my office at firstname.lastname@example.org . An email also does not retain my office, but can help you get an appointment set if you prefer not to call). I am happy to discuss possible representation with you. Any information in this communication is for discussion purposes only, and is not offered as legal advice. There is no right to rely on the information contained in this communication and no attorney-client relationship is formed. Nothing in my answer should be considered as tax-advice. To ensure compliance with IRS Circular 230, any U.S. federal tax advice provided in this communication is not intended or written to be used, and it cannot be used by the recipient or any other taxpayer (i) for the purpose of avoiding tax penalties that may be imposed on the recipient or any other taxpayer, or (ii) in promoting, marketing or recommending to another party a partnership or other entity, investment plan, arrangement or other transaction addressed herein. Note that I am only licensed in Georgia and thus cannot practice in other states. I am also required to advise you, if your question concerns bankruptcy, that the U.S. Congress has designated Ashman Law Office as a debt relief agency that can help people file bankruptcy.
If he files for paternity, he will end up paying child support. At his income, that is inevitable. He will likely pay more than what he thinks, as the basic child support obligation for his salary, and two kids, is $1749. Below is the link to reach the Georgia Child Support Calculator.
The first rule you should follow is to not take legal advice from your children's father. If he hires an attorney, don't take legal advice from that attorney. You should hire an attorney as soon as possible to protect the interest of your children.
If you don't work and maintain physical custody of the children, based on his income, he will pay more than $850/month. If you were not married and both of you are on the deed, you are simply tenants in common. If you want to stay in the house, you will have to come to a separate agreement regarding the house.
