What you are doing is great but do not get your hopes up on what your W said when you saw here drinking. Her emotions are on a roller coaster just like yours. Right now you are on different rides but going thru the same things.
She will at times be very distant and not want to be around you other times it will feel like old times. Do not take either one personally. These feelings will come and go as she trys to figure out what she wants. You need to have a thick skin or be like water on a ducks back and let these things roll right off you.
Being out of the house is not a bad thing. It will give both of you space. You to GAL and to have a safe place to allow your emotions out. But when you are with her you must be happy and have a PMA.
She will benifit from being away from you and it will allow her to miss you. She will be relieved at first but there will come a time when she will miss you. It may take a while but paitence is key here.
You need to stop worring about what she is doing or when she will call. Take care of yourself, get your med right and put your effort into your kids. they need you now more than ever.
Keep up with reading any books you can find. It will get easier and your emotions will not be all over the place. Vent all your frustrations and anger here, alot of people will listen and help you out.
There are alot of positives in you sitch, you just need to relax and be her friend right now.
