what do I do? I bumped Into a guy I have know for five years Now he is calling me to go out to coffie?

.I first met him in some classes I was taking for work five years ago.I have seen him from time to time and we said hi. Now he is calling me to go out to Coffee.How do I say I only want to remain friends with out offending him? I am in my fifties and still haven't learned to do this tactfully. I can't just say Im just not that into you because that would be to assuming.why is he doing this now .He appears to be twitter paited he never was before.
