Husband going out of state for work for a year while I’m pregnant

I am currently 4 weeks pregnant and have 2 kids.. along with cats and dogs. My husband just got called on a job site across the country for the next year and is expected to leave in a month.. I live with my parents and have support.. but we also were divorced and just recently reconciled. (It’s a long story) anyway, we both have a lot of debt and this would be a good financial opportunity, but I’m also nervous about it. Would it be reasonable and worth it for him to go? Idk I guess I’d like to hear others opinions and advice if you have any.
