Men don’t believe women choose to be single because men don’t choose to be single.
Being single is the default position for women. That’s why men pursue women and not the other way around. Women only shift out of their default position when a man comes along who makes them want too.
Women want men who make them not want to be single anymore. Men want women because they don’t want to be single. There is a very specific difference there.
It’s also why men can’t figure out why their attempts at shaming women into getting married don’t work.
Women want men who make being in a relationship better than being single. Companionship isn’t enough. There has to be an increase in happiness in her life when she is with a man compared to being alone, that requires active participation in building a good relationship.
If that isn’t there, she will choose to be single.
