Should be clear
Everyone has said the same thing...basically, so you should know the answer.
Taking it further, even when you are married you can NEVER symp a chick. She may not cheat but sex will become perfunctory and you will be slipping further and further down that ladder. Hey, its okay once you are both 70 and the kids have left because you will be mates and grow old together, its only, what, 40 years? of pointless sex and boredom.
When women have a child they have a life project. Men associate with work. That is why we die younger, usually 2 years after we retire. Women have the kids, grandkids, etc.
Let the chicks deal with chick issues and we men stick with male issues. My honest advice is a hell of a lot more extreme than this, I have toned it down for you. I have sypmed, been played, felt shame, ALL THE ABOVE. I didn't wake up until I was 36 years old. Maybe you HAVE to live it to chnage it? The "naturals" don't, but perhaps some of us do.
