Dear Prudence,
My cousin, who is two years younger than me, is pregnant. Last week I found out she has been telling people I am the father. The two of us went on an overnight road trip to visit our grandmother around the time her baby would have been conceived. This trip was well documented on her social media. How do I get her to stop telling people I am the father? And how do I address people thinking I slept with her?
