Questions about marriage in general...but being married to a cop specifically?

i was married to a lying backstabbing cheating stealing no good for nothing low down dirty dog of a cop for 15 years ...he was ******* around with a on duty and all "THE BROTHERHOOD" knew and wouldnt do a damn thing.....i dont think you need to worry about her i think we need to talk her out of marring a cop...i know every cop in our county and i also know that everyone of them cheat on their wives...i have no respect for any police officer i have ever know ...with your little badges on power trips thinking your better than everyone...
