I really don't know why it makes a difference to me, but it has in some small part.
B/c if she's having a MLC....then you can blame it on that, instead of you taking the blame for her feeling like she does.
This is almost typical, anymore, for a LBH. So many men start their thread by telling about their WAW. Then they find out about OM. After that rocks on for a short time (and the H can't deal with things as they are), then he tries to convince himself, and others, that she's in MLC.
Yes, I agree....it makes you feel better to think she's in MLC than being "just" a WAW.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
