Leaving work

Hi all, I need to get something off my chest and you guys haven't failed me before! My fiance and i are planning to move abroad after the wedding which will happen in april next year however in not so many words hes convincing me to leave my job on the basis that I will only have 2 months where i will properly be able to work. (Background we are predicted that in Septemberof next year we would be out of this country) there will be a time where for 4 weeks he will have to stay overseas to do the whole visa application and stuff and is wanting me to come with him. Im thinking this will be difficult with my job as i am already taking leave for the wedding and honeymoon and i wont be able to take 4 weeks off again soon after. I will also be living with his family for the time being until i move. His parents only mentioned once i dont have to work but havent pressured me to quit and neither has he other than giving me food for thought in terms of how quick this will all be and my job will take a lot of my time. My mum has mentioned to me countless of times not to leave work and I dont know what to do in this situation. We both want to move abroad and thats what i want to. Any advice?
