I think that her comment about not feeling love for you, yet asking you what the two of you should do, is telling.
Although I wonder if there is a cultural consideration there. Are you both "traditionalists" in your ideas of family, couples and marriage?
I notice that you mention going to MC so I suspect there is at least some modernized relationship thinking, at least on your part. I also notice your W mentioned you do not speak her LL. She could simply be using the LL as a reason things won't work.
Do you think there might be an affair going on? Would that be a deal breaker for you?
