Well its not all doom and gloom! I've been happily living in sin since leaving uni with my GF and she always knew I was into flying as I used my gliding tales to chat her up in the first place. Once I got my power ticket she started coming with me and although she was nervous at first she now loves looking at the nice houses and the trips down to the west country to see our repective sets of out-laws. When I've been out of work she has been kind enough to pay for fuel for my group plane to keep me current.
I'm not sure if it has any bearing but we're in our mid-thirties and have not opted for marriage or children as yet. She encourages me to pursue my dreams and I encourage her.
Doubtless when we get married and have kids we'll become as self destructive as everyone else.
Perhaps the rest of you lot should try living in sin and not procreating immediately in order to figure out if you're compatible before it becomes contractual. I may edit out this last paragraph as it sounds a little harsh.
