Wow some fat fingers in my post above...
con't should be can't
quo should be quit
Yes, Don, your sausage fingers suck.
While I agree with the sentiment, the actuality here comes down to the communication between the two individuals involved and most likely that of a counselor. Putting such a "touchy" subject on the net for "advice" really only clouds the actualities experienced. Posting on this site just leads to a bias and further personal accounts that don't really have too much bearing. By this I mean we will see those who are FFs portraying their experiences, those who may have gave up the fire service for family, you most likely would never see.
So yeah, like you and others, I couldn't give into such an ultimatum, I worked too hard and too long to reach the career of FF to just give it up. I'm biased. However, I have seen a give and take and despite the OP saying he has since quit his volly gig, that isn't how he originally phrased it.
Regardless of personal experiences or advice given by other FFs here, the only true way for the OP to work this out is to work it out with his fiance and discuss everything and even better to have a counselor involved to mediate that communication. Seeing a counselor should not be viewed upon poorly because it is great what can be accomplished by having that environment to communicate in.......and with that, I'm also biased because I have personally experienced it working.
I fully agree on this one. Seek professional help (Both of you) and make the decision.
