What is the best way to get someone back for cheating on u when all he did was get mad that i was hanging out with my ex thinking that i would cheat

He cheated on you because you were hanging out with your ex. Why you were hanging out with your ex we do not know. Now you want revenge on him for his cheating.

I think you are both too immature for a relationship. A committed relationship does not involve revenge, mistrust or oneupmanship. Focus on what you want in life and then find a partner that supports and embraces your goals.
