Could he be turned off by a delayed email reply?

I’ve been emailing with a man for some time now, that I briefly met on a skiing holiday. It has gradually shifted from friendship to something subtly more romantic. For a while, we emailed each other almost daily. Then, I got this really intimate email where he straight out said that he can see himself in a relationship with me. I’ve just come out of a long term relationship and I needed to think if I was truly ready for a new relationship. So I managed to use 6(!) full days to respond. In my reply I explained the situation, apologized for making him wait, and openly admitted to having feelings for him too. But now, I have this fear that I might have ruined everything, by waiting so long to reply?! He usually replies within a day, but has not replied in two days now.. I'm so afraid I might have offended him. What do you think, could I potentially have spoilt it by waiting this long to reply to him? Do you think I will hear back from him eventually?
