Welcome to the site Melissa! I've been with my man since he was an instructor in 2002 and there have been ups and downs -- but mostly "ups'!
If there is communication, trust, and respect you guys will do just fine. The worst part of our relationship was when he worked at Mesa and he was constantly switched to different bases and in 2006 we only saw eac other 3-4 days each month since I was in PHX and he was in IAD. Things are great now that we are living closer to his base and see each other regularly. I amd trying to get a lot of travel in now before we have a baby (whenever that happens!). It will definitely ne hard to be a single mom part of the time.
We're here to support you through it all!
