This about it. When women get angry for dreaming the guy was cheating, the guy just stay stoic and chill her up. When she is on her days and hormones make her mental, the guy is there buying her food and making her laugh. When she is pregnant and the baby is hurting her, the guy is there, doing all he can to help her. When she is depressed needs to go to therapist, the guy just drives her there, no judgement.

Women do provide emotional support to men, but it is mostly by being there and being faithful. Apparently just existing and not fucking other men is too hard for some women. The truth is that if she calls that emotional labor, it probably means she is not that interested in the man, which is very sad and men shall see that as a red flags when she bring that up... it probably means she is damaged goods and will never truly love you. I don't suggest you to leave her if you are getting sex and status from such relationship (which still does not require her to move a finger), but don't ever marry her.
