How to get away from a married man

Move? Can you provide more details?

Call his wife.

Just threatening to call his wife should be enough.

Stop talking to him? Don't answer his calls?

Send your underpants to his wife in the mail?

Don't call or answer his calls, don't open his emails or texts.

I think this is a loaded question. It starts with you. You know how to get away from this man. Gain some strength and choose to leave him alone. It wouldn't hurt to get mad about it. He is using you and abusing his relationship with his wife. Not fair to either of you. Best of luck
