To correct one part of what Kess said... because you are married, if there is on base housing, you can opt to live there if there is space available. My ex-husband is active duty CG. We lived in base housing for several different locations. We also lived off base, either by choice or when housing was just not an option where we were stationed.
Underway time depends upon the size of the ship. You can pretty much guarantee he will be underway for half the year. The smaller the ship, the shorter time of deployment. An 87 will go out for 5 days, be home 5 days. A 110 will go out for 10 days, home for 10 days. A 210 will go out for 6 weeks, home 6 weeks. The ice breakers will go out for 6 months and then will be home for 6 months. If he is at a Sector, with the exception of days standing duty, it is pretty much a 9-5 type of thing, weekends off. So it all depends.
He will have to be 6 months out to tour complete when he can get in contact with a recruiter. He will have to take the ASVAB again, he will have to go to boot camp. He MIGHT be able to go to DEPOT (Direct Entry Petty Officer Training) if his MOS in the Army translates to something in the CG. That rarely ever happens. So please be prepared for him to go to boot camp for the full 8 weeks. If he doesn't, then that's a bonus for you (and him). :)
The current wait for ME school is about 2 years. So again, be prepared for a wait on that end of things.
I can tell you I am divorced from my Coastie. However, the CG had nothing, absolutely nothing, to do with our divorce. I loved my CG life, we just were not meant to be husband & wife. We are now very good friends and encouraged our son to become a Coastie. He is loving his life as a Coastie as well and hopes to make it his future. You will find that CG life is very good, very family oriented and while he may be underway for half the year at varying increments of time... it probably won't be as stressful as Army deployments.
Thank your husband for his service so far. And thank you to you as well. I wasn't an Army wife, so I dealt with different circumstances but I know how hard it is sitting home, worrying, wondering, just wanting your friend to be there with you. Hope you are together for the holidays.
