Congrats to Sir and Lady Stinkalot
Congrats to you both.
I've been married to Ros 16 years last January. We've had three kids, aged 11, 9, and 8. I wouldn't trade then in on anything, although I do contemplate eBAY, and power tools, when they are tired and crabby.
It's been mostly smooth sailing. As she thinks I have no major vices (apart from the 4" Engineers in the shed) and don't smoke, don't drink (much), don't bet, don't consort with other women, and I return home to the family home more-or-less the same time every day in a sober and reliable fashion, she sees fit to indulge in my various hobbies. She knows I don't like buying crappy tools, so I don't, and she's quite happy letting me maintain my motorcycle in the manner to which it has become accustomed.
It's not all beer and skittles, but my life seems to be richer than the people I know older than ourselves that have each other, and work, and that's all. She has very minor and occasionally annoying quirks that sometimes drive me nuts, but I'm sure that I display traits which have the same effect on her. The hard part, which seems to cause people problems, is that you have to realise that people are different, and the do have their own way of doing things and seeing the world. You have to accept and respect this, if you don't, then the relationship isn't going to last.
A lot of marriage is give and take, although many years ago I found that my wife, it's better to give, and then take when she'd not looking! It's certainly not worth arguing with her, the female side of her family shows a remarkable amount of independence and stubbornness (traits passed to my daughter).
Anyway good luck!
