I want to thank everyone for their advice...even those I don't necessarily agree with. She's not just my girlfriend...we're getting married in August. I could agree if I already were a firefighter and she didn't like it; we'd have to break up. But I wondered if I was being selfish trying to become a firefighter after I'm married. Thanks again everyone.
I hope things work out for you both. Maybe have her talk with some other wives and see their feelings and views. From what I have heard most wives/husbands' fears subside over time. Coming home at the end of each shift is great re-enforcement that there are more safeties in place than dangers.
Best of luck to you and forge on with your goals, all of them... things have a funny way of working out.
