You decided it wasn't appropriate to call the police on someone "constantly" (seriously, constantly?!) stealing your stuff and selling it, but it was appropriate to spray paint his guitar...or for that matter, continue living with him and then also spray paint his guitar? Sheesh. No, you'll be just fine, even if he didn't drop the charges, but dang I don't think anyone ought to hire you if this is any evidence of your critical thinking abilities.
