Thanks for all of your input. I had another girlfriend at the beginning of flight training that wasn't too big on the idea, so she got the shaft sts after a while. My current one is just not looking forward to a cold bed half of the time. I think when it comes down to it it is an issue of trust between us, although she wants a family man who'll be around to help with homework etc. We're talking about it. I just don't want to be stuck (like some of you have said) as an RJ Capt making 65K because the schedule is good, and an upgrade to the majors would mean a tough schedule for a while.
-I also think that living together is like having an ejection seat. When it all goes to crap you just pull the handle and let it crash with everyone else involved going down too. Thats no way to start a real marriage.
