My little sister (20 years old) is in a relationship with a man that our family believes is married. He lived in Michigan and moved here to Tennessee after his mother died so he could be close to his father and cousins. Well, he met my sister and they started dating about 3 or 4 months ago. They are now engaged to be married. But the thing is that all of his cousins have told my sister that he is already married to a woman in Michigan. He denies this, and my sister believes him. But he also has a womans name tattooed on the back of his neck.... and he swears that "Becka" (the name on his neck) is his deceased grandmother. Our whole family has tried to get her to dig a little deeper just to see if he's telling the truth about not being married, but she refuses to do so. He couldn't even get his income tax return because he had already filed with someone else in Michigan. My sister keeps getting calls from a woman saying that she's his wife. That would be enough to make me want to find out for sure. But I'm not her, and I can't make her decisions. Maybe she doesn't want to find out. Maybe she's scared of what might be the truth. Who knows. He's been caught in many lies since he has been seeing her, and he calls her fat and stupid all the time. But my question is this. Should I keep on asking her to find out more about him, or should I just back off and let her find out the hard way? I'm very concerned about her, and I don't want her to be hurt. But I don't want her to think I am trying to run her life, either. Any suggestions?
