My virtual-real relationship

I've been taking my son to the section for about 5 years now. Back in 2013, I liked one of our assistant coaches, well, I liked him, I just liked his appearance. But my inner voice said, "Oh, he's a real bug." We didn't cross paths until the fall of 2015. One fall, I was expecting my son, he came up to me, started asking where I live, how things are, and then we talked about politics, our views didn't match, butThey didn't argue about it.

I decided to find him on social networks (I used my second anonymous account) and see what his views were. Well, I found him, went to his Odnoklassniki page, didn't see anything political there, I liked it for the sake of decency and that's it. Then I got a message: "Who are you, you know me, let's get acquainted." I told a lie, like I was living in another city temporarily and so on. We talked for about a week. And then he suddenly disappeared. And it seemed to me that he guessed in real life who was writing to him. I felt unpleasant, I liked talking to him.

Three months passed. I received a message: “Why don’t you write test-antibiotic.com, where have you disappeared to?” I replied. It so happened that we started corresponding on VK (in my real account), but there was no photo or last name there. He wrote that he lived alone, and if he needed to move any furniture, he offered his own.help . He really walked around, said hello, smiled sweetly. Everything is fine. Once he wrote: "Why do I always write to you first?", and I thought about it. And I remembered that somehow he is always the first to end the conversation: "well, bye-bye, I'm off to cook food, wash the floors." This really bothered me, as if he wanted to get rid of me.

Then in July I posted my real photo, let him think, he knows who I am. He liked it, wrote a comment: "nice photo." And disappeared. The last time we talked was on July 23. Then I don't write to him and he doesn't write to me. September came. We went to the section again. And somehow he says to the child quietly, so that no one can hear: "is your mother's name Olya?"the child says "yes". We just bumped into each other recently and just said hello. He's silent again. I removed him from my VK friends in a clever way (he didn't know about it, that is, there was no notification). Today I saw him, and I felt somehow dreary "maybe it was in vain". Advise me what to do. I think my option is -forget , say hello in real life, as if nothing happened.
