Is he feeling more than friendship?

We got hit by natural disaster. This man, who is my close friend (we're both married) called me within few minutes. I didn't have time to call my parents to see how they were doing. His sister called him while he was talking to me, so I guess I was the first one he called to see how we were.
Ever since that day we text every day and he text me every morning just because. To say good morning and to have some talk. I think he needs me as an emotional support, someone to say all these insecurities he has now.
Is this too much for friendship. Is it ok to have that in me and not his wife.
I mean I like him a lot, he is a good man, but we never had that deep connection before.
