These I do like spending time apart, but when I do even if just a few hours. I miss him and can't wait to get home. I know he is the same too.
Consideration. Balance... getting what you're giving without having to draw a road map, get 'em a gps, and fill their gas tank before it occurs to them.
When you realize the extent of the other's flaws, and love them anyway. When they see you at your worst, and love you anyway. When you can submit to the other's strengths, and vice versa. When you can deal with the fact that no relationship will ever be 50/50. When you can deal with the fact that there's no such thing as "happily ever after," nor should there be. When you accept that even though you never know what will happen in life, you both can control how you, as a couple, will ultimately respond. Essentially, I think selfishness is the root culprit behind roughly 50% of divorces. Too many people go into relationships asking themselves "What's in this for me?" rather than "What does my partner need from me?"
and so, my fellow americans... ask NOT what your partner can do for you, ask what you can do for your partner!
i would say that mutual respect as well as trust can help relationship last longer. Even love plays an important part in keeping relationship going.
Money and power of both parties are the two obvious ones, and I would add a good dose of dependence and a lack of self-reliance.
The secret to my relationship is the secret to my life.... Dont take everything so seriously. Laugh with each other, constantly. don't act like the other person's flaws are a personal affront to you. Smile and poke fun of their flaws instead of allowing yourself to get irritated. lighten up. I used to turn relationships into heavy drama so I had to learn this the hard way.
