Like everything else in life, all of these 'experts', red pill communities, pickup artists, etc have pros and cons.
I think it's best to pick out the good parts and not to let the toxic parts consume you.
But from what I have seen and read here and elsewhere, pick ups, relationships, marriages, divorce busting, etc all essentially boil down to a common theme: be the best person you can be. Have purpose, have confidence, stay in shape, etc. It is easy to become complacent in marriages. It's actually almost impossible to avoid, especially when you have kids. I blame men for not recognizing the emotional needs of their spouse. I blame women for not always communicating those needs clearly, and for straying when her needs are not met 100% of the time.
Rock, we've been through hell. Everyone here has. Learn from it and hope to come out stronger.
I will give you an easy tip to tell you are meeting her emotional needs. If she constantly wants to $&#% your brains out you are meeting her emotional needs. If she does not than Houston you have a problem and better fix it fast.
