So it's basically me then. I wasn't attentive enough perhaps. I wasn't very good in bed maybe. And for all intents and purposes I wasn't bringing in an income. So it's me, I am the failure here.
All relationships are 50/50.
In my case, I blamed my wife...until BD..then I initially blamed myself. In reality, we both had issues. The way we interacted was broken and neither one of us knew how to fix it. Neither had the skill set.
The good news is you can change. You can grow. You can clean up your 50%. You can behave different. You can interact with others different. You can make different choices. You learn new ways to communicate. You learn as much as you can about attraction and seduction. Drop unattractive traits and add attractive traits to your behaviors.
You have been given a gift, even if you can't see it, we can. Take this time to become happy alone. That doesn't mean you don't interact with others. Just don't make your happiness dependent on having a woman in your life.
She has just as many issues as you, but she most likely will not grow. At some point, she may see all your changes and like what she sees. She will most likely miss her friendship with you. At that point, you will be completely detached and hopefully have a whole new set of skills to deal with her.
