Perhaps you are enquiring about additional spending/pocket money. The ruling on this is that it is not necessary, but if the husband happily gives such additional spending money, it will be regarded as a gesture of goodwill and good spousal relationship from the husband; hence commendable. Nabi Sallallahu Alaihi Wasallam said,
خيركم خيركم لأهله
“The best from amongst you are those who are best to their wives”. (Tirmidhi, Mishkaat 3252)
6) Yes, the wife has the right to request for privacy. The things that are discussed or done at home are an Amaanat. If the wife requests for privacy the husband cannot disclose any such private matters to his family and friends nor can the wife.

المجالس بالأمانة
“Meetings are confidential”. (Abu-Dawood 4869)
7) If he is going to place were there is no Haraam, then she cannot stop him. However, if he is going to a place of Haraam then she should advise him not to go there. (Aap Ke Masa'il Vol. 6 Pg. 334)
