Lior,
It isn’t a Torah value to unwarrantedly break up a family.
Also take into consideration that she is sinning
Your assumption that a woman wanting a divorce is acting capriciously, unless she can provide you with clear-cut evidence of abuse, is fundamentally misogynistic. Sometimes valid reasons are difficult or terrifying to articulate, and some abuse can be hidden from all but the victim. There may also be other valid reasons not involving abuse, such as an irreparable loss of trust.
Also, two wrongs don’t make a right. One spouse acting badly does not validate the other spouse acting badly.
If a couple is going to beis din for divorce proceedings, the home is R”L already broken, and it would take both of them to rebuild it. This cannot be forced on one of them.
It is both callous and maleficent to unwillingly force a person out of a marriage he put his life into building and put him into a situation of being divorced when it is unreasonable and all other options have not been exhausted.
Your attempts but failures to make statements like this gender-neutral (writing spouse or person, but then exclusively using he and him) are revealing.
In a marriage, do you think it is only the husband who puts his life into building it?
