The only part I am unsure about is the fact he is not technically my “step son” anymore since his father and I are divorced.
For purposes of claiming a dependent, a step-parent is always a step-parent, even after a subsequent divorce or the death of the biological parent. This is also confirmed in publication 501 on page 18, where it says "Any of these relationships that were established by marriage aren't ended by death or divorce."
