Ladies!! Sorry if this is kind of long. I have been holding this for the past month and i feel like im going to explode

My husband and I are going to have our church wedding next year in his home country. We have been saving for the laat 6 months. Recently his brother moved in with us. Since that day my life has been a complete disaster. They work together now. So its been a month that i dont go out with my husband. We cant even have a conversation because he is always with his brother. My husband started a second job to save more money for our wedding. WEll.. He has been sending that money to his home country and MY MOTHER IN LAW IS DOING SOME UNECESSARY CHANGES TO HER HOUSE.😡😡😡😡 I HAVE BEEN BARELY SEEING MY HUSBAND BECAUSE OF THIS SECOND JOB HOWEVER WE HAVENT SAVE MONEY BECAUSE HE KEEPS SENDING IT! He and his brother send money every friday. Idk what has been going on but since he got here my husband says he is going to be saving the money because he doesnt trust me with it. Even though i have shown him our bank acct. We have saved over 3000. In 4 months. Please tell me what should i do. Every time that i bring this subject up we ended up fighting.

Im really to leave him, but then i think how happy we were before his brother got here. 😭😭😭😡
