I dated someone a year ago, I'm 26 and he is 29, but after 2 or 3 months he started to pull away.

He had recently been dumped by his ex, but this isn't the reason apparently, he said it was because he wanted to focus on his work and he had family issues going on. I was upset but we didn't speak since then. I spent some months just focusing on myself, and am in a really good place right now compared to how I was last year.

Last week he started liking my photos on Instagram, so I added him yesterday as it was private and he's followed me back. We haven't spoken, should I message him? I would be interested in revisiting but feel like he should reach out first considering he was the one who ended things.
