I thought we were friends but now he ignores me?

I recently reconnected with an old fling after he reached out saying he wanted to be friends. I thought "why not?" since I've moved on and have been dating someone else for nearly a year. We hung out for over 5 hours outside a coffee shop and I realized I had been missing his friendship. He's a great conversationalist even if we're not right for each other. A few days after that though, he went completely off the radar, and then a few weeks later pictures of him with a girl surfaced on Facebook, and they're apparently an item now. He only barely acknowledges me when we see each other around as well. I'm now thinking that he wasn't sincere about his offer of friendship - would it be safe to assume he was just using me/wanted to get in my pants? And now that he has a girlfriend, I'm of no "use" to him anymore?
