Husband driving me crazy

My husband hates America. He’s a travel nurse and we have 3 kids and still struggling. Especially with how high prices are. He does so much research and is one of those people that will find and learn everything he can. He randomly will say how much he wants to move to Europe and go into HUGE rant sessions on how it’s way better and the quality of life is way better then here and how it’s cheaper and overall just something he really wants to explore. Tonight he asked if I would ever consider moving there and how we should book a trip soon to go and feel it out. I understand his logic but I’m not sure moving with 3 children who are still young ( 8yrs, 6 and 3) is smart? He says you’ll never change your life unless you take risks and how this is something he’s really passionate about doing but I wanna get some other peoples takes on it. We don’t have much family around who helps other then my mom. So that’s the biggest thing in my life the only one I have. Other then her we don’t have much of a support system so that’s not really an issue. I just fear that’s a big jump. It’s not like moving to another state it’s literally another country. I have traveled the US but never outside and he’s only ever been to one other state so there’s not much travel experience idk I’m just nervous about it all and if he’s dead serious this is a big thing since there is 3 children. What would you guys feel/think????

If your partner wanted to move to another country with you and your kids how or what would you say? Lol
