However, it requires that you subscribe to a certain ethics/morality that I don't think everyone is going to sign up for
Why do you need to hold yourself to a certain level of ethics/morality when women couldn't give a fvck about ethics/morality? The nature of the woman is to find her soulmate, and she'll throw any other man under the bus if she thinks she's onto "the one". Women believe in 5hit like destiny, and if their emotional buttons are pushed enough, she'll believe she's stumbled onto it.
especially for more inexperienced/newbies who are taking baby steps and others who have just have standards against that type of thing (ie if she's unfaithful to him, then she could be unfaithful to you too and is not a keeper).
Let me tell you this... A good 80-90% of adult women are NOT keepers. You know what else? Most women are on their best behavior in the first 6-9 months of a relationship. If you want a "keeper", you're gonna have to filter through these women as quickly as possible. You're not going to successfully screen a "keeper" on the first meeting. You essentially have to throw darts and hope you get a bullseye. If you've never thrown darts, then you need to practice in order to have ANY HOPE of hitting the bullseye. So what if these women are unfaithful? Dating her means that you've just gotten a little bit better at throwing darts. Once you realize you didn't hit the bullseye, then you throw another dart.
What
you're doing is making sure you have a dart that is new, sharp, and that you have a clue on what the rules are for playing darts. However, every time you throw one, it lands on the ground because you don't practice and every other player clobbers you in the game.
Then where do you draw the line? Suppose the woman is married and has a family but it's the only woman you have chemistry with and is excited about you and is willing to divorce-rape her hubby, tear up her family, and then enter a marriage with you, would you at least draw a line in the sand there?
First of all, I've had chemistry with multiple women. You don't marry the first one you have chemistry with. As for divorce raping her hubby and wrecking her family, that's her decision. All I've done is made her realize that she's not happy with her choice in a husband. Also, if she's been married or has been alpha-widowed, then she's not marriage material. Again, she falls into that 80-90% of damaged trash that you throw away.
Even you have to have limits.
My limit is to not marry trash. Everything before that is fair game.
As for taking "baby steps", it looks like you've been taking them since 2009. When I joined this site back in 2001, I went out and fvcked up multiple times. Two steps forward, one step back. It took me about a year before I found myself successfully dating a woman that I had cold approached. And then I started dating a SECOND one. That was the moment I knew I was doing something right because I suddenly had an abundance of women... I had TWO while most other schmucks had one or less. If I could have given myself an award at any point in my life, that would have been the moment.
