the wallet of your husband is considered as his property, so it is not right to take money from it without is approval.
In the mentioned case, the best thing would be to reach an agreement between you and your husband where you can save and share your money in fair and satisfactory way for both. If it is not possible, starting two separated accounts could be another option.
Islamically, the wife's money belongs to her and she can use in halal way at her discretion; therefore the husband has no right to prevent her from them unless there is a previous agreement that allows him to do that.
With prayers for your success.
