I had a fight with my husband

He has applied for collaboration with an organization that doesnt have a good reputation and I had told him multiple times that ppl who collaborate with that burn their futures. But the money is good.
So last night he told me he has applied for it and I was shocked. I started shouting and I told him that either its me or that application. He said he will cancel it as he saw my reaction. But the thing is, that he says he is tired of trying so hard and not getting anywhere. He has a good job but the pay is not enough and barely covers our daily needs. So he says he is embarresed that I ask him to take me to a vacation abroad. He admits that I only say this once a year. Im not acquisistive at all. Now I feel guilty that I said I like to travel, even if I say it once a year. But if I dont talk abt my desires, then what should I talk abt after all?
Maybe I should keep quiet and say nothing abt anything.😔
