This is probably a stupid question. Is this normal?
The only time a question becomes stupid around here is when it gets asked over and over with the same answer being given each time. So...no, not a stupid question.
Yes, this is normal and as you know the increased drinking is only another failed attempt or quick fix to dull the pain and turmoil.
The cycle you see will be around throughout this crazy ride. I'm 6 months D'd and still see this very same thing. The more distant I am the more she pursues and tries to control.
You must stay consistent with YOUR emotions and actions. Reactions are no good here. Do for you first and then also "do more of what works" when it comes to her. There is a balance to all of it that is hard to keep but it's doable. These mlc'ers have tons of similarities but at the same time each one of them is a bit different, so what works for one may not work for another. Bottom line though is you must stay consistent, don't bounce around with her.
You have a wonderful perspective on all of this, and you know your situatiuon best. Trust yourself.
