That depends.

It’s up to you whether or not you want to do that.  It’s important to consider that it might feel uncomfortable to you, even if you haven’t spoken to your partner about it, because there’s an opportunity for dishonesty.  For example, if your partner were to come home and find money missing from his wallet, he might naturally be annoyed.  Also, it’s a little suspicious to grab ahold of a wallet and remove money, so the theft would be obvious.  If the money is spent before the theft is noticed, your partner might wonder where it went.  But if you’re okay with that, then I can recommend that you do it if you need money.
