These are really good suggestions - and they should work for both genders, both ways (who doesn't appreciate a heartfelt "I'm sorry"?).

OTOH, this is among the many articles where it feels like it's the wife's right to be emotional and unreasonable (anybody is unreasonable when s/he is emotional), and it's the husband's duty to be patient, supportive and loving.

Why is the opposite not even mentioned...? Does the author perhaps thinks the average woman is unable to master her own emotions?

Why it looks like women in general (and feminists in particular) demand equality when it's convenient (to them), and gender-different behavior when it fits their agenda?

When it's the man who's all emotional and mad and enraged, he's usually told to cool down, man up and behave like an adult: "No tantrums and hissy fits, you're not a child anymore".

Why is this never told to an angry woman?

IMHO, no serious discussion about equality may happen as long as double standards are held: you cannot have both.
