I don’t know how old you are but I should have made a move many, many years ago before it became to late. My advice is this…..check, double check & triple check that your wife is on-board and knows what she would be getting into. It’s easy now to support her husbands dream (it’s still a dream) but what happens when she actually has to pull roots and move? I’m not saying she won’t, I’m just saying………..
From your point of view you have to understand how many years of working you have ahead of you. If you are 30 and the boys 5 that means another 15 years until they are grown and gone. That makes you only 45. Plenty of time to make a decision.
If those boys hit school and become rooted with their friends it will be all the harder to pull the pin. Your wife becomes involved at school, she makes friends with the other parents, sports.. yada yada yada. You won’t be going anywhere.
I have another angle that I won’t get into online but you seem to have a handle on things pretty much. Where you are at now is make the dream come true or chase the dream?
I wish you luck working through it. Just don’t rush and the answer will show it’s self.
