My DF wasn't around when I was growing up. In March I contacted him and we spoke for the first time in over twenty years.
He answered questions I had. We also arranged to meet. My idea. We met. It went well. We then arranged to meet again. Both meets were my idea.
I decided not to send him a message arranging a third meet up. I wanted to leave it to him as I had arranged the first two. The last time we met was the end of April. I haven't had anything since then. He hasn't message or arranged to meet again. And I don't feel like I want to do it as it has so far been me doing all the messaging and arranging. I want him to put some effort in rather than it all being me.
Surely, if he wanted to meet again or stay in contact he would message me?
So, considering this, AIBU not to send him a Father's Day message? I don't feel we have the kind of relationship to do this. Though, he did send me a message on my Birthday back in March after we first starting speaking. He also bought my DC an Easter Egg on our first meet up.
