What was your filing status? You didn't file married did you? If not legally married your filing status can only be single (or possibly head of household if you have a dependent relative like a child, living with you who you support).
There is no way your boy friends situation can affect your tax at all of the BF is not on your tax return.
Your BF might be your dependent if his total income for the year was less than $4,200, he lived with you the entire year and you paid more than half of his total support for the year, but again, a dependents situation cannot affect your tax.
