The smart man adapts to the conditions around him.
The current conditions dictate this:
1. Why get married if for many sex stops after marriage and you get cheated on and possible alimony. Having your life disrupted
2. Why get into relationships, when they cheat on his, or damage his life in one way or another
3. Many groups are taking the side of the female as a default, so if she chooses to issue disparing remarks or damage him, no body will care
4. Why be responsible and be accountable to a person who is not grateful and wouldn't do it for me.
Right, a smart man with a low SMV with no options.
A high SMV man with options:
1) Why get married -- you enhance your social status and have children, your wife knows you can get another woman at the drop of a hat so she has to keep giving you sex or you may get another girlfriend, mistress, and have allot of variety in your life so she better keep you happy and do what you want.
2) Why get into relationships...you have a stable girl while you can go and meet other women and jump if you meet a hotter one. You have the social proof you have a relationship and that will enhance your game. Your woman has to keep you happy because she knows you can easily get pvssy and won't go into a 10 year dry spell if you have to break-up with her or if she breaks up with you.
3) N/A you have your own social group. She's probably using some orbiter as an emotional tampon but you made her your alpha-widow while you are still dealing with other hors.
4) You have options and are not buthurt.
I've addressed all of your questions from an abundance mind-set, and chad-high-status male fantasy. I mean even I can have an imagination, and I feel the tables turn if you are a high SMV guy and have options period. MTGOW is a low-SMV guy cope that has a difficult life anyway because you don't really meet woman and tend to hold on to any woman you do get for dare-life and they take advantage of that. It's still a Black-pill cope. If the SMV is low, then its just low.
