Guys - What are his feelings? Is there a chance?

A couple of weeks ago I started an affair with an old friend. We're both single. We were never very close. I know he was very interested in me one and a half year ago, at the time, I was in a relationship and I refused him. I've learnt to look at things a guy DOES and not SAYS. He ended friends with benefits prior to our talk about relationships. He spent a lot of time with me, texted me a lot or called. We laughed a lot, he looked at me often smiling. At his place he kept making sure if I have everything I want, in public he was a real gentleman. After spending some nights at my place he cleaned my car windows from frost. He initiated the 'relationship talk'. I loved how he behaved towards me, very respectful and attentive After 5 weeks of this bliss he went away to a soldier's training for a week. He came back saying he realized he hadn't fallen in love with me. It broke me. We broke up. He sounded and looked very sad that he hurt me. I know that he has a thing for older women. We have lots of things in common and there was no reason to suspect the absence of strong feeling towards me prior to him leaving. We have great sex. We never had a conflict, everything went smoothly. Suspiciously so. Any insights?

I had never expected to fall in love with him, but I did and very Quickly because of how he treated me. I don't think I pressured him in any sort of way.
