I completely respect that Ashley and think it's wonderful that you and your partner have this sort of honest dialogue going on. None of us can rescue every snake we see in trouble or we can well slip into a hoarding situation and get overwhelmed. Rescue isn't rescue if you can't do right by a snake (not saying you wouldn't hon of course).
Perhaps since you cannot personally help this snake you could post enough info here, in case another member would be interested in this rescue. Also if you have a herp club or a reptile rescue in your community or within reasonable driving distance you could contact them about doing the rescue. If all else fails, you could also direct the snake's current owners to this website and encourage them to learn enough to at least give this snake the right care while they search for a proper new home for it.
