The Living Force
Yes I don't think anybody (including the woman when she's the hurt one) is actually asking for sex of any kind either in any kind of way, covert or overt. Just when there's a love growing (but not at the ideal love state yet), that possibility exists since both sides either have been before or are heading in that direction.I'll jump in if you don't mind. There's nothing wrong in itself to comfort someone with sex as long as both participants are consenting and both adults. But I suspect you don't understand the female psyche that well if you think a woman will confort a man who's not her partner with sex without expecting this man to become her partner. You don't give so much of yourself for nothing. In such a case, one is giving everything and the other takes without giving back. That's creepy.
A grown man who's depressed and asking for sex, overtly or covertly comes off as immature, needy, weak and that's not attractive at all. But in itself you're right, it's not wrong. It's just not the best a man can do. Sex doesn't mend a broken heart, it doesn't right the wrongs of the past, and while it can give a boost, the only way to heal is to face what is wounded inside you.
The purpose of these books is to show what a man and a woman can be at their best, they show how hard it is to get there, and the joy that can be found when one overcomes obstacles. They show how a couple can help each other overcome these obstacles. Sex has is part, because it is an expression of love.
As for Silent Melody, I am siding with @hlat and advise you to read again.
Emily and Ashley love each other, and that's a not a small difference. Althought Ashley has a more brotherly love toward Emily at the beginning, and suffers when he crosses the line. Because Emily gave everything and he took without giving back. Because he was so immersed in his problems, that he didn't saw all the wrong he was doing to her until the deed was done.
Emily proves to be a hell of a woman when she refuses to marry Ashley, the man she loved for years, when it is presented on a silver plate, because at that moment, it isn't right, because at that moment Ashley proposes out of guilt, not out of love. The book is all about how Ashley realising his love as morphed into a more mature love, he learns to give back, to let go of the past.
In my case the girl came to me (who was actually the one via whom I got hurt via her having a boyfriend) thus I wasn't covertly or overtly doing anything, in fact I was in a room she never went anywhere near but either she went and found me or was told about me by someone who found me. The girl even though she had a steady boyfriend put her face inches away from me and played with her lips with her fingers in a way she knew drove me wild because we had done this in German class (it was an independent learning class from tapes). She obviously didn't overly mind being my partner in this way since it had happened before though it had to be somewhat of a strain on her since she now had a steady boyfriend. There in my case was the addition that she knew she was the one over whom I was hurting. By pre-existing sexual tension I mean either a growing love or a past relationship or both. I had originally phrased this as true love/obsession/good friends possibilities (good friends being a past relationship that had stopped via separation and obsession being mostly one sided like with my situation).
