Hello You.
I remember your previous post. Have you met "L" yet? I think just ask him when you talk to him next, "Have I done something?" "Do you need some space for a bit?" "Has there been something gone off?".
Just ask first before backing off, because if you do back off straight away, he may think your avoiding him. So if he says yes to the question/s above, then just give him space. But if he says no to the question/s or whatever you decide to ask, then just talk to him normally and be there for him
You can PM me more if you need more advice. I don't mind. But I am here for you, and I do remember you from before, so if that helps.
Good Luck Babe.xox
