please confirm the astrologer's analysis

it is but we're not in a relationship yet , for now we're each others person of interest

In this case, I would still assign the 7th to the other person.

In this case, I would still assign the 7th to the other person.

...or the 5th?

I wouldn't go there, the 5th implies a love affair, at the moment he is the "other".
However, try using the 5th, what comes up?
