I think the key is for each to be able to compromise. Love isn't enough. We all have our preferences on how things are dealt with and you have to learn to give-and-take in how those things are handled. What is show stopper, what is something you're willing to change for her, what is something she's willing to change for you?
An example for me is that she knows I'm watching every Cowboys game. I'll let her know when the game is going to be and she knows every honey-do, errand, dinner date, etc has to be scheduled around that Cowboys game and she accepts that. Likewise, I know she's going to get her nails and eye brows done every 2 weeks.
I know I have to put my clothes right side out and in the laundry basket so she doesn't have to flip them while doing laundry or she's gonna get pissed. She knows she needs to put her damn mail out of site because I don't want to see opened envelopes on the counter top.
I know I can't take her to eat at Olive Garden, under any circumstance. She knows I won't ever eat a Papa John's pizza.
I pick up the dog crap in the yard and she cleans the kitty litter.
Compromise.
