Relationships can be ruined in infinite ways,
but there are only a few paths to long term success.
The keys are empathy, honesty, good-will and non-aggressive communication styles.
I think if one could survey all relationships and examine those with feminists and those without, one would find that exactly the same percentage of couples split up in both categories.
Being independent is not necessarily an obstacle to success as long as both sides enjoy being equally so.
But if one is highly dependent or clingy while the other is struggling to achieve individuality and fulfillment, it will fall apart irrespective of sex, gender, orientation or values.
When values and needs are at odds and the couple cannot create mutually workable solutions, failure is inevitable.
In my view, feminism is as beneficial to the man as to the woman. She works, which means she contributes significantly to their survival and prosperity. He helps at home, which means he appreciates how much work is involved in cooking, laundry, cleaning etc and never takes her domestic chores for granted. Both feel more appreciative of the other's contributions. By arriving at consensus in their decisions, neither dominates the other. An independent woman is more interesting. She brings new conversations to the relationship, helps short circuit the effects of familiarity and boredom. She is more sexually honest, communicative, active and more likely to reach orgasm more easily. He is more likely to enjoy pleasuring her as much as his own pleasure. If they have kids, he gets to enjoy a much closer relationship with them, and she regards his role as being just as important as her own.
The only exception would be if the man was the type who believes it's her duty to obey him, who cares nothing for her needs, talents to be of use in society, and who refuses to help equally with housework and child rearing or their other projects. (Yet I can't imagine that a feminist would couple with such a man.)
If she did find herself trapped and controlled by such a person, then feminism might be one of her few routes to freedom, usefulness in the wider world, and personal fulfillment.
An unhappy woman only results in misery for the whole family.
