Newbie: Is this MLC and how do I GAL?

[Some Day]

I've come to the conclusion (thanks everyone) that I need to DB harder. The moment I start distancing, my H starts texting asking if I'm ok. He also starts inviting me to do things. Once, I start saying no, i'm busy, he is sure to start asking questions (what am i doing, who did I go with, etc). How do I dettach and go dark/mysterious without being "mean" or him thinking i am angry at him? I've always been an open book with him and this will be a big departure. Just want to make sure I don't shoot myself in the foot here.
