Boy JW, sounds like I wrote this post myself! I'm also 25, married, and my wife and I are wondering the same things. I'm sure this is old hat to a lot of posters here, but new to many others who I'm sure are wondering the same thing.
A buddy of mine who's been in for ten years (and his wife) have given us some great advise and encouragement. I have some medical conditions that we also need to consider. Anyways, he has a great family and doesn't regret ever joining. We asked them both if they would do it differently, and they both said no. My wife and I like stability, something you won't get in the aviation community. And to be straight up–we want what God wants for us. If we join out of His will, that's a scary place to be, especially if I don't get to fly for whatever reason.
Feel free to post some more questions and I'll tell you what I've been hearing from friends. It's great to hear of your concern as someone who is in the same boat.
