Wow, what an awesome opportunity! But definitely a hard decision to make because there are so many factors to consider.

Have you drawn up a list of pros and cons? This might help you see things more clearly, sometimes the negatives seem like they overtake the positives until you see it on paper IYKWIM?

Consider whether or not you think that moving is worth the sacrifice for a few years of your life. What will that sacrifice mean for you in the long term? Is the result what you really want? Also - in 5 years time, do you think you will really regret that you didn't take up the opportunity and wonder what could have been? Or, on the flip-side - do you think you'll regret giving up DH's job and moving away if the business works well?

Do you have proof to show that the business is profitable? Is your DH passionate about it? (It sounds like he is). Sorry for all the questions! You don't have to answer them on here, they are just questions that I think are important to ask yourselves.

Good luck deciding
