It seems like a complicated situation, @jon72. I don't really know a lot about handling money so I'm not sure how much can I help! I'd suggest to talk things through with your wife as well although I get the feeling that you've already tried that. Still, if you haven't, DEFINITELY sit down and talk to her. Make her understand that you Love her very much but that you don't appreciate how your sister is interfering with your Lives and marriage. Be as kind and reasonable as you possibly can - it's important to make her understand that you're on your side so avoid being aggressive. If, after ALL of this, she STILL takes your sister's side then I'm not sure what to suggest honestly. At some point it's worth asking yourself how much does she truly care about you. Still, I don't want to bring your mood down. Talk to her first. I'm sure there's a way out of here. Perhaps it won't hurt to talk to her sister as well although I would wait before considering doing that. I hope your Wife will listen to you and understand your concerns! Keep us updated if you wish to do so. I hope the situation will turn out to have the BEST possible outcome for ALL the parties involved! Also, please don't be hard on yourself. It seems like you've been able to accomplish quite a bit! If you're still feeling so down, perhaps a therapist may help? Just some thoughts for you! I know it doesn't have much to do with what you've asked so decide by yourself. Stll, wishing the BEST of Luck to BOTH You and your Wife! Sending many safe, warm hugs to BOTH You, @jon72, and your Wife! KEEP FIGHTING AND KEEP ROCKING LIKE YOU'RE ALREADY WONDERFULLY DOING ALL AND ENTIRELY BY YOURSELF!
