I am a married woman. Why do some men like to play jokes on me?

You should consider why these people disturb your life. Did you contact them first, or did you inadvertently give them some opportunities to contact you? I guess although you are disgusted with their behavior, for some reason, you shouldn't completely ignore them. Think carefully about why you met such a person. What they say must be based on some of your words and actions. In other words, some of your words and deeds make them want to flirt with you.
