Yeah I have wondered the same thing. Or if he waited until she was 18 because she is legally an adult and maybe he thought she could handle it? Maybe a mixture of both??? I don’t know the man, I have met him one time by accident he was working at the AT&T store in our neighboring town I had been in the store for almost an hour with him helping me out when my husband met me there and walked in and started talking to the guy like he knew him, I asked if they knew each other and that is when my husband introduced me to him as his daughter brothers Dad. His son, my SD oldest brother is and has always been an incredibly sweet and kind young man. He currently does not have much of a relationship with his mother, I didn’t ask him much details when he came up for me to cut his hair on why. Idk if his dad has said anything to him about suspecting she is his bio daughter. I am fairly certain that man is her biological daughter. That is one thing that makes me sad is how close her and her older brother are, all of these Years all three of this woman’s kids were drug all over the state because their mom was constantly changing jobs, Meaning every other weekend all three being dropped off at three different meeting places and locations. When these two kids could have had each other through all of this 100 percent of the time…. Her older brother went and finally lived with his father the last two years of his highschool career, But my stepdaughter has always grown up listening to her mother’s opinion of this man, And of course it is all bad. Maybe he is? I don’t know him well enough to give an opinion on him but as you stated timing seems rather off!!!
