Even though the numbers are different, I know something about this. My daughter-in-law is 10 years older than my son and used to work for me. (That’s where she met him when he volunteered to help me, I had no clue). When William finally came clean on both, I had to take a huge step back. Not going into the backstory here, but I kept a close eye and didn’t say anything. I always prayed that G_D would let him be happy and for me to support him. G_D answered that prayer. I have two beautiful grandchildren. I know two totally different scenarios, but I know somewhat how you feel.
