[ Family ] Open Question : Need advice. Would it be okay to send this to a family friend!? Please answer! (10 points for best answer)?

Knew him for over 20 years and found him on Facebook just three months ago. He knows who I am by the way. I didn't know who the person in the photo was after I posted a photo of me and him on social media and he found me and said it was him and even said he was friends with my aunt. I told him it was nice to meet him again and he didn't respond though. My cousin wrote on his Facebook wall saying "how's it going Brian? You were talking to my cousin, Serena (me) the other day" three months ago and tagged me in it. Would it be too late to post a comment and say: "I know this post by cousin Theresa was made three months ago and I'm a little late in commenting, but, I remember you from when I was a kid, just didn't know what your name was at all, but I recognized you in the family album. My mom told me many years ago that you moved away to Mexico when I've asked about you as a child. I just want to let you know that I think you were one of the coolest and nicest people I've met in my childhood :D" Does this comment sound flirty, weird, or odd? Many people have told me it was. He's almost 50 and married so I have no intention on hitting on him.
