Dissolve a friendship?

I had a guy friend, we use to hang out, talk, text and enjoy each others company (platonic) nothing more.

Anyway, I told him I liked him as we have known each other 3 years. Well he started acting weird/nervous. His behavior changed. I meant I liked him like your a great guy.

So I sent him a card and wrote a note telling him that I like him as a person and that he is a great guy friend (I never hinted anything about a relationship).

Then I made this point and stated that even if we both mutually agreed to move out of the friend zone and tried to take it to another level that it couldn't go past that, which is why I prefer to maintain

our friendship as is because of this. (I said this because his family is overly religious and want him to marry or date only girls of the same religion). I am not of his religion.

This guy was calling and texting non-stop after this. But I actually saw the guy yesterday and to my disbelief he acted like he didn't see me, so I walked up to him to say hello (just being polite) I didn't mention the note or anything.

He seemed uneasy and I thought we resolved the issue.

I felt I did my part to clarify things and continue being a friend but this guy's behavior is odd. What would you do? Cut all ties? I am at that point now. By the way the guy is 29 years old by the way.
