The blind date was originally with someone, but you said to be friends first, so this is not very good for the woman.

The woman will think that maybe you don't like him, so that's why you say so. This may be a polite refusal.

So in the days to come, then the woman will not put her heart and soul into it. Because she is just a friend, she doesn't need to contact you so often.

Anyway, your statement is definitely not very good. Since they don't match, don't stay together. I don't think it necessary to get along with ordinary friends.
