Need advice.

My husband and I have been split up for 3 months until November we got back together. Well he had been trying to get a job working on power lines in Puerto Rico (1950 miles away) he goes for 120 days.. he just found out yesterday that he's leaving in 5 days and he's going to take the job with or without me. He wants me to quit my job and go with him but that consists of a lot of flying considering our daughter goes to her bio dad every other weekend. I have never been on a plane and I'll have to be by myself the first time I get on one. It's an experience I'll never be able to do again but at the same time I'm afraid because I'm leaving everything behind. Is it fair for him to give me 5 days notice that he's leaving without me if I don't wanna go? This should be a decision we make together right? The only way I'll be able to see him for 4 months is if I go with him and I am terrified if I don't go, he will think I'm not supportive and I've heard so many stories of traveling men cheating on their wives. Am I being over dramatic that I won't see him for 4 months and I'll have to move in with a friend until he gets back because I have no where to go.
