So you got cuckold, eeh, don't despair, now is your awakening.
First ask yourself: "Gee do I want to do that all over again, put my dick, faith, love and money into a women just to have her use me again?"
If the answer is "no" then take up the 3 steps of MGTOW, go as far down the steps are you want:
1. Celibacy: First overcome your need for pussy. We can teach you how to become comfortable with yourself, self-reliant, and enlightened.
2. Renaissance man: Lets make an exercise regime, journal, daily todo list, time to make your self a better person, not for pussy, but for yourself.
3. Control: Look at that women are digging the new confident you, should you care? You have learned to control "want" now, you can moderate desire. Like an alcoholic that is truly over his alcoholism you can drink now, because you can moderate yourself and not let the drink control you, in short (and if your slow) I'm saying you can fuck now, because fucking is unimportant to you, you neither care about fucking nor about not fucking, you are above it.
Once you reach step 3 you control your relationships. She makes demands of you, she disappoints you, you say "there is the door, bye" she will come crawling back, or not, you don't really care. She not going to cuckold you now, because she knows you will kick her out and laugh as you do it, not cry. You got the upperhand, now if she is smart she will try to get the upperhand, the only way a women can.
She will start asking for raw sex, start "forgetting" where she is in her month. You always wear a condom, keep it with you, discard it yourself, or better yet you got a visectamy or intra vas device (but still wear a condom because god only knows where she has been). She not going to entrap you.
Lets say you are open to children though, sit her down, ask her, then get out the lawyers, judge and notary and make her sign the prenup, no you are not getting married, no no you are binding HER to a civil contract (Don't recommend doing this unless your in a country where prenups cover custody of children, USA or Canada are not one of them, Britain: just no) It includes a DNA test too.. what is that?.. she is objecting, you point at the door.
If she is smart, she will know to fold'em. Your virility will outlast her fertility by decades, she can feel her self getting more sterile like a clock ticking down, yet see you age like fine wine. She needs a baby more then you, in fact you don't need the baby at all, nor the pussy, you don't need anything but what you provide for yourself, you are practically doing her a favour! You are agreeing to provide for the child YOU own collectively, not her alone, she fucks up, fucks around, she will loses the child, she will lose everything.
If she stupid, well you really should not breed with stupid ones, or worse she will try to cuckold you anyway, send her out the door, you had no faith in her anyway, you only have faith in yourself.
