Wow...this is a rather loaded question, if ever I've heard one.
(takes a deep breath)
Well, this is my definition of love in a nutshell: "the selfless giving of one's own self for the emotional, mental, relational, and spiritual betterment of another". Jesus gave more of Himself to us than we could ever give to Him in this life. He was pure, holy, righteous, and sinless, and He endured so much pain we had to invent a new word for it: excruciating ("out of the cross"). I will freely admit that many days go by when I don't feel His presence in my life, and it is so easy to get depressed, and feel sorry for myself. In fact, I'm going through a day like that as I write this.
What kind of love do I want from my wife, when I get married someday? Well, my one and only relationship (thus far) was based on selfishness, paranoia, fear, and lust, more than anything else. I remember my ex-GF saying to me many times, "I don't want to corrupt you", and yet that's exactly what happened to the both of us. I can't speak for her, but my heart was torn and confused many times over, not knowing which way to turn. We tore each other apart in so many ways, and even though I miss her sometimes, I'd never want to be around that kind of situation ever again.
Quite a while ago, I made a list on my computer, of the qualities I want in a wife. Here's a few from the "character traits" section of that...
1) She must have accepted Jesus as her Savior, and also posess a strong moral foundation.
2) She won't be unfairly critical, judgmental, or harsh, especially concerning the failures of others.
3) She'll be understanding and forgiving, yet not a "pushover" in any way.
4) She won't be afraid to hold me accountable for any foolishness or irrseponsibility on my part, and will expect the same in return.
5) She'll be brave and capable, yet minding of her foremost need for God, and secondary need for me to protect her as well.
6) My attempts to defend her honor won't be met with insult or offense.
7) She'll be both trusting and trustworthy in matters of love, loyalty, finance, and sex.
8) She'll be honest with me when I ask her questions, and won't resort to playing "mind games".
9) She'll understand my desire to avoid premarital sexual touching and intercourse, and do the same herself.
10) She won't want children for at least the first five years of our marriage, if at all.
11) Her sense of humor will be full of joy, yet clean and not intentionally offensive.
12) Her smile will melt my heart like no one ever has.
13) She won't swear excessively, if at all, and especially won't take God's name in vain.
