As someone else said the key is to set expectations early.

My best advice to new husbands is if you don't plan on going all out for things like birthdays, anniversaries, valetines days etc. for the rest of your life don't do it the first year. Once you start you're stuck, because if you ever stop they'll take it as an insult. (I'm not saying be a total slacker, but I see guys going way overboard the first year and I'm like man you are setting youself up for a world of hurt a couple years down the line)

Same concept goes for fishing, if you want to go fishing every weekend in the fall you should have been doing while you were still dating. That way she can't come back with "remember when you used to spend every weekend with me" when you ask to go fishing.

Going of 14 years, have two kids and I still fish at least once a week from June though April.

Wife gets her girl nights out and girls weekends and I get my fishing trips. If you want to last you both need you separate activities and equal oppurtunity to do them without bitching from either side.
