Yeah, this is one reason we normally suggest you start with three, not two, as a minimum.
So how to get rid of him since you are not allowed males. You can always try Craigslist, assuming you are in the US. You can look for other pullets there too. But accept that once you let him go you no longer have control of him. His fate is out of your hands.
You might find your State or Country thread in the "Where an I? Where are you!" section of this forum and chat with your neighbors. There is no telling what kind of help they can give you, either taking him or getting new pullets.
