Never get involved with married people. It's bad karma. It will mess you up bad, especially if you know the person they are married to. You risk getting hurt emotionally, legally, and physically if you get involved. I know from personal experience. I had a guy tell his wife, who I was with that he would kill me if he ever saw me again. Not worth messing up someone elses life and yours. Find someone who doesn't have any moral delimmas pressuring them. It just makes it easier on you an everyone else around you. Plus, if they are willing to be unfaithful to one person, that's a sign about how they will treat you as well. My mom has been through three marriages and countless lovers due to being unfaithful. Love is not some game that you can just pick a name out of a hat. People who do are likely to hurt you as well.
