Does this seem too desperate?

I am very single only have male friend that I speak to on a regular but very distant. I decided to friend request a guy in my neighborhood. He did accept my friendship. I did like a few of his photos including of his granddaughters. We are both 52. He did accept my request. I sent him a msg. on Facebook. It was a compliment saying nice photos. I asked if he was a trainer and he only replied no.

I was so embarrassed as I feel he have no interest in me at all.
Then later he was on my Facebook story and then liked a photo that I had posted. I don’t want to seem desperate.
