I agree with Seren - continue doing what you were doing during the night, even if it was sleeping! Do not allow his drunkenness to deter your night. This does lead to detachment which, in turn, can lead to clearer thinking and decision making in regards to your situation as a whole. At least for me, that is how it worked. Once I was able to detach I was allowed more room to think (since I wasn't worried about reacting all the time). I have a much better handle on things now. I'm not perfect, and neither is my relationship with RAH, but we are still together.
I wish you well. Keep coming back!!
