Does my Ex's friend have a thing for me?

I was with my ex for 9 years, and he had a friend he knew from online gaming. We both used to talk to him weekly, occasionally visit (doesn't live local), and I used to chat with him by myself and we developed our own frienship.

When I got engaged to my ex and started planning our wedding he started to distance himself from us both and then stopped responding to both of our calls and texts.

My split from my ex was messy and nasty. A few months later I text him just to ask how he is doing and hoped he was ok, but he hasn't responded.

My friends think it's because he has a thing for me so cut us both off once we got engaged. But I'm concerned he knew what my ex was doing (cheating). I hope not as he's a really decent guy and I thought our friendship was real. Men's opinions please x
