I'll bite. I think there are myriad reasons for LD. Is it ok for my H to be LD? Sure. It just doesn't work for him to have an R with me and be LD. It doesn't work for him because I become unhappy and he doesn't like that. It doesn't work for me because I become unhappy.
Frankly, I have plumbed the depths of my H's LD and asked him repeatedly if he is upset with me for the kind of things that kept me LD in my prior M - lack of trust, mutual disrespect etc... He has denied any of those issues. Additionally, given my H's lack of sexual involvement prior to dating and marrying me I think that there is more to this than relational issues between he and I. So, his reasons for being LD are different than the reasons I was LD. Does he have valid reasons? Probably but given that he won't discuss them, doesn't even self identify as LD, sees everything as situational that leaves me in rather the conundrum.
