Ok...so your LL isn't being met. Fair enough. Your tank is empty. And you feel unloved and used. Who wouldn't. You've expressed this to him and he has not responded. I do think that Jen is right that you really need to spell this out to him. We're guys, we're stupid. You need to be very blunt to him that if you LL is not met, you will be gone.
I know my LL is Affirmations as well and now that I have other people in my life giving me that....I feel like a million bucks. It works. And he needs to understand how much better his M will be if he can give you that.
48 Hour rule always makes sense. If for no other reason more than you'll face the conversation better...logic not emotion.
