Hi Jalimon,
I don't know. There is always money, or almost always money and power in any relationship.
One joke that is too true is that wives get paid far more per SOG than SPs.
Men (almost always) give their wives lots of money, directly or indirectly.
And there are so many kinds of love. Tolstoy said every unhappy marriage is different. QED.
BUT...I think most people in a conventional love (BF/GF/spouse) relationship would say that you do not pay the girl directly for each SOG, or each hour of sex. So, for conventional people... but we are unconventional...or so I thought!
[Note: Careful, some of you. Don't assume about me. But you can ask, of course. (BTW, I think men can be jerks too. Well, "me too"...as one example, ...there is, I think sadly, too much truth in all that. And also some lies.)]
I agree with someone else here. A higher form of love, probably a more eduring form of love, is where you care about the well-being of the other person. You would visit them, or they would visit you, in the hospital, for example.
(Note: "If you want a friend in Washington, get a dog." Or so cynics have said.)
When we say BF/GF/spouse, most of us want commitment. Someone who will be there for us. Someone who cares deeply. Someone who really tries to get to know us over time.
But I think (you can disagree) that real love is more about giving than receiving. More about action than feelings. And has no relation to time. BUT, once you have found a person or God or that mountain top, you typically do not want to leave.
THEN...inevitably, you must leave. You must work, usually somewhere else. You become distracted by the million things of life. You do the responsible thing, and earn money or do work. "I come and I go"...this coming and going is rough on lots of relationships, probably all.
Be careful what you wish for. Treat her well; she's a real soul, just like you. (Even if, in a way, she is "playing" you.) Try to spend more time with those you care about the most. (We all love many people...and all those different types of love are more similar than they are different.)
And.... I love sex. (Wherever it may have started and wherever it may end.) Man, whoa! And I do love (at least for some time) a girl who enjoys sex with me. And maybe even, like I, loves me for that time. Sex, love and rock-n-roll. (OK, it was "Sex, drugs, and....")
Final note: We ask sometimes "Is she playing me?" .... and usually to be played is a bad thing. It often means: "She is lying to get more money from me." But remember, this is a customer service business. Don't you "make nice" with your customers? Don't you sometimes find yourself liking your customers a LOT? (Not always, but sometimes.) And don't you also say "Well, work is over, I'm going back home to 'real life'? Saying "Je t'aime" can mean so many things.
So, it is a good thing to "play out a fantasy" sometimes. If you do not want that (there is a degree in which I do NOT want that)... to be fair, you have to tell her and explain what you want. Of course, she may or may not want to "play that game"... go along with that. Reality is my fantasy.
Woman are NOT perfect. But everything considered, I really like most women. They are weird and different (but so are most men in another way), but it's usually fun to talk to them. And they are usually nicer to us (men) tha we deserve. (OK, sometimes a woman can be a PITA. And certainly misunderstandings can drive you crazy.) Go listen to Patsy Cline.
