How to deal? in Life Lessons

How do you deal with being caught between your dad and your husband? So for example - financial accounts, my dad has control over mine and he tells me some about it but I’m not super involved… he won’t talk to my husband about it much at all. So one one hand I have my dad telling me things and on the other my husband is saying the opposite - my husband is out making big “fun” purchases with his money while I’m left paying for groceries… my husband has a full time job and does side work, I only have a part time job that’s not steady. Financial things really stress me out especially when both of them have different opinions. I know I should be listening to my husband but sometimes I disagree (like when he is making fun purchases, and I have to use my savings to buy groceries) my dad sees that and tries to tell me that’s not right but idk what to do…
My husband has also agreed to try to work things out with his mom and sister being rude to me… I just don’t know what to do…
I just feel like I’m being torn apart and everyone is trying to stab me in the back…
