The former Fulham boss, whose current deal runs until November, said that he will assess the situation after the next three games.
"We have two games and a friendly and I will see that through and at the end of that, that is when I will sit down and say yes or no," BBC Sport quotes Coleman as saying.
Wales lie bottom of their World Cup qualifying group ahead of the clashes with Macedonia and Belgium, and reports suggest that Coleman's future could hinge on the team's performance in these remaining fixtures.
"If that is the case, then I wouldn't want to work for people who judge a situation like that, because it is short term," said Coleman.
"In the space of two games a lot has changed... perception anyway.
"That's football, I understand that, but if that is the case and this is a win, draw or lose situation... we make a decision after that, I am not sure I want to work for anybody like that."
Wales have won just three of their 12 games since Coleman took charge.
