HELP.. I NEED TO KNOW WHAT TO DO 10 POINTS PLZZZ?

if this guy is going around bad mouthing you to other people / then that shows that he has no cl / no respect for you . because if he did he would of kept his mouth shut .here's what i learned about a liar.when a person tells one lie guess what they continue to tell more lies to cover up for the first lie they told.he already said he's not apologizing /that shows that he has something.if i were you i'd tell him i don't want no part of him / his lies .so i think it's best that i leave you to your madness/ focus on my own madness.
