His income will not be considered for what is called the "Means Test" and will not effect your filing staus as far as your eligibility goes for you are not married. However, if his extra income effects any of the catagories of expenses you list in Schedule J, it could.
For instance, if he were to pay more to your portion of the rent (which I presume you currently split), or if he were to pay any other expsenes on your behalf, it would lower the amount you claim you pay for that expense and, consequentlly, change your income to debt ratio. If his new contributions changes the numbers so much that you are now solvent, that is, having an excess of income at the end of the month after you paying for your listed expenses, you will no longer be elegible to file a Chapter 7 bankruptcy, presuing that is the chapter you are filing under.
