THE #1 KEY TO EASILY ROMANCING YOUR WIFE.
Be considerate. That's it. It seems so simple, right? It really is, however it may be a bit more complicated than you're thinking. There is more than meets the eye with being considerate.
Let's start with 2 things that "considerate" is NOT:
1. Being considerate is not the same as "caring." Caring, although important, is really just concern - which does often result in action - about another. For example, someone can care endlessly about how another is doing after the loss of a loved one, but if they wanted space and alone time to grieve and the "caring" person insisted on spending the whole day with them, this wouldn't be very considerate, now would it? A considerate AND caring person would want to give the friend what ever it is that THEY need for their process, whether it be space, time, or company - not just what THEY think the recipient should have, but what that person wants and needs for their own unique personality and situation.
...Which brings me to my next point...
2. Being considerate is NOT doing "unto others what you would want them to do to you." Now, you could argue that it is, in the way that you would want to TREAT them as you would want to be treated (because you would want to be treated with what I like to call "considerosity"). But specifically what you would want to be DONE unto you, is unique to YOU. If you are CONSIDERATE, you are always finding out what the other needs/wants and trying to meet THEIR need (within reason, of course).
So you want to romance the most important person in your life? BE CONSIDERATE TO HER. Do what SHE WANTS, treat her how SHE LIKES, complete the tasks that SHE HAS ASKED FOR, take her to places & events that SHE WANTS TO GO TO, and even talk about the subjects that SHE WANTS TO TALK ABOUT.
Not sure exactly what she wants? ASK HER. She will love it, because it will make her feel important, valued, and loved! And be ready to stifle any critical reaction or judgement when she tells you what it is she wants/likes, because chances are, you won't agree. Remember, this is not about you or your opinions. This is about HER. Romancing her is as easy as selflessly just giving her what she's asked for. It's not rocket science, but it does take a bit of effort.
To avoid having your efforts criticized (and consequently feeling like the whole act was futile), try this: before you complete the task that she was asking you to do, ask her HOW SHE WANTS IT DONE. I don't believe in a "point system" for love, but if I did, this would earn HUGE POINTS for you! How would you do this? Shoot her a text and say, "Hey when I come home from work today I planned on hanging that picture you had asked me to hang for you. Is there any particular way you'd like this done?" Not only are you setting an expectation that you will be completing a task that's important to her, but you've created anticipation, AND shown her that you love and respect her enough to ask HOW.
Another example of asking HOW she wants it is if you're planning a date she's been asking for. You might say, "I know you've been wanting me to plan a date for us, and I'm about to start. I don't want to give away all the juicy details, but is there anything in particular that you've been wanting to do? I know you mentioned a tour… Were you thinking of a Segway tour? Or a particular type? I've seen architectural tours and even cupcake tours. I want to do what YOU want to do!"
Now she's excited - and it's because YOU'RE... SO... CONSIDERATE...!
THIS is ROMANCE... and it's EASY!
