can a suitor see a niqabis face more than once, even when attraction has already been confirmed. he wants to see her face because doing so will convince him even more to get married to her, even though he already intends proposal. he still has some reservations and seeing her face will solve them

He can see her face and her hair, and she can wear normal, respectful clothes in front of him that are not the usual abaya and hijab, so that he can see and decide, inshallah. This is not something that should happen quite often. However, if he saw her the first time but felt he did not see enough, and therefore wanted to sit and look at her again, this is allowed, inshallah. After that, no more.
