Question: how long should you ignore your ex?
Answer: If you feel like it falls between a 1-3, do 21 days. If you feel like it's between a 4-7, do 30 days. And if it was really bad, and between an 8 and a 10, do 45 days. Realistically, though, if you ended it, the 21 or 30 days should do the trick.
