I am confused?

So I am in need of some help from you lovely ladies. Recently I have been offered a position at a marketing firm that is very well respected. I went through the interview process and got the job! ...but here is my dilema: my boyfriend has also been offered a job that involves traveling all over the United States. If he takes this job, I would never see him. He has reassured me that if I come along, he would be able to provide for us with just his income. I do not mind leaving our home to go with him but I am not sure how to tell my family or my job about this change. Please help ❤ what should I do about telling everyone and up and leaving in about a month and a half?
