Frankly, I went through the same issues as the OP in my 20’s because I was always told, by the women of my mothers’ generation, that being a nice boy is what women wanted. They don’t. Not even the 29+ crowd.
You’ve got to challenge them, give them something to love you for AND something to hate you for. Make the thing they love you for a powerful thing (remember their middle name, birthday, some random thing they told you that’s obviously important to them)and the thing they hate you for a lesser thing like toilet seats etc. (see Little Plastic Ninja’s post).
I did the same allegedly chivalrous things that you seem to be doing and you’re finding out as I did, they don’t work. Women don’t respect what we see as chivalry (as proven by the witnessing in the thread) they see it as weakness because by the time we reveal the other side of our personality, if there is one, it’s too late. By then you’re on the express train to friendville.
I’ll share with you Auto the two things that should cure this seemingly terminal singlehood.
Be yourself. Pay attention.
First. Repress nothing (aside from the really weird shit) and give her only what she’s earned when it comes to respect.
If you’re busy, be busy, don’t drop anything for her unless she’s in real trouble. If she calls and says “I need help, my car’s broke down in this really rough neighborhood and I’m scared” Drop what you’re doing and go to her. If she calls AFTER you’ve made plans though, that’s tough. Say “sorry honey, I’m going out with the boys, I’ll call you later”
Second. Details matter. Women are classic overthinkers. They worry, nay, obsess over countless things, often at the same time. Men’s brains typically don’t work that way. If you remember some minor (often meaningless) detail that she’s told you and can recal them at will, you’re in like Flynn. Extra points for noticing things that she doesn’t know she does (i.e. biting her lip while she thinks etc) and telling her about it. Caveat. Don’t remember EVERYTHING, makes you look stalkerish and weird. Women are all about the details, it’s the reason handbags, earrings and jewelry have such a huge market. A woman will notice things about another woman as she walks by that a room full of trained detectives would miss in a standing line-up. It’s how they are.
Ironically, the “nice” guy ends up treating a woman as an object to be treasured instead of a thinking, breathing, human companion. If you do this, she will turn on you like a monkey with a stolen cupcake.
Truth is, you can treasure a woman without letting her walk all over you, in fact, that’s the only way to happiness, you’re your own person, she’s got to be hers. As soon as you find the boundaries of your internal balance, you will find a woman. If you continue to be the guy that drops everything and comes a-runnin everytime she calls you, you’re going to be alone a LONG time.
