Husband gives away ALL his money

My husband is not originally from America. My husband sends huge amounts of money back to his family     . I honestly don't mind him sending his mother money( I've sent some to her too) but he send money to uncles, cousins, brothers etc all who are able to work. Yesterday our son asked him for money for his field trip and he told him to ask me because he does not have it. I gave it to my son but latter had a convo with my husband about it. After seeing his bank statements I was pissed. His savings is empty and his response was his brother needed a new home since his last one was destroyed. I reasoned with him but let him know he's supporting them way too much. He then basically chewed me out about it. He said he came here to America for the sole purpose of being able to support his family back home. It's like he's putting everyone before his son and I. I just don't understand the amounts he's sending. Last month he sent over 60k ( to diffrent people). And is now suggesting I get a job ( I'm a stay at home mom btw) Am I wrong for being upset? He also suggested we put off ttc our next child for a while.Opinions please
