You are in a good place. Your W is on her own journey. You can not do anything to control this trip. Come here and read or vent, we will listen. Give your W space, she needs to heal himself.
I would not ask her anything unless you can have no expectations. Sometimes asking them questions will be thought of as pressure. You do not want to do anything that can be thought of by your W as controlling or pressure.
Your need to start working on you. There is nothing that you can do to help your W.
She is giving you a gift. It is time!!
Use the time wisely to make yourself a better person. Look in the mirror to see what it is that you can improve. GAL.
Read some books on depression. Both for yourself! And for W. Believe none of what she says and 50% of what she does.
Read the resources from this site.
You must detach and leave her alone. Keep posting and asking questions and we will try to answer them.
