Would you get mad if your husband was giving his mom every week for her cigarettes and pop every week which is almost $100 when your trying to get a home fixed up to move into with a baby on the way?

I feel bad for being mad but he has a brother who lives at home and works and dosent help pay for anything. When my husband does give her money, ( his car insurence is in her name) she gets mad because he gets behind sometimes cause hes giving her money. Btw im 20 weeks pregnant so we alse have a child on the which pisses me off even more about it.
