DEAR ABBY: My mom's boyfriend wants to spend time with my 16-year-old sister and take her places all the time. He wants to cuddle with both of us whenever we sit on the couch and gets really upset when we don't want to. He's my biological father, but I have known him only for a year because he left my mom when she was pregnant with me.
Now he wants to play "dad" when I already have had a dad all my life. (Mom was married for 11 years to another man.) I'm 14.
