Am I wrong about this guy's intentions?

I've known this guy since I was in middle school. We briefly dated in our teens. He's a few years older. We've stayed in touch here and there. He's married. We all ended up at the same bar one night to watch a band. His wife was really drunk. She tried playing with my hair and I swear when I left she was in my face like she wanted to kiss me.

Not long after he told me that they invite people into their relationship. One night he was texting me saying I'm one of his oldest friends and I mean so much to him. That he loves me. Since then, he hasn't spoken to me. It's been a while.

Am I crazy that I feel like he wanted to invite me to join them, but I didn't seem interested, so he just stopped talking to me?
