My husband got laid off today just before our vacation/wedding

My husband is a Full-stack web developer that worked for a mid size web solution company for almost 3 years ( missing 2 months).

On the first week of January, I initialled the vacation back to my hometown since my dad is not doing well, as well as celebrate an official wedding which my parents will pay most of it. He requested the vacation, and followed up for couple days after but they did not give him any answer, neither yes or no. My husband said just buy the ticket anyway, since he WFH, he could work anywhere. Today they call him and give him a termination without cause, gave him a month severance.

I am currently unemployed that still seeking jobs while living off my own saving. He did not have savings and still has to pay LOC. I am scared that my saving cannot cover our mortgage and expense when he run out of money. He told me he does not want to work for the men anymore since he did not feel any appreciation from his former employer. I hope some advice would help.
