I occasionally read your thread and I think I may have written you something a long time ago.
I am very, very sorry to see things are where they are for you, but now that they are, I want to recommend that you consult a family law attorney immediately. Don't walk, run.
There are things you can and should do to protect yourself, your son, and your relationship with your son, and a good attorney can tell you what all these things are.
Another thing I want to warn you about is any hint of physical violence between you and your wife, because that could be the basis for a "kick-out" order that sends you packing.
If all your posts are true, and I'm sure they are, then you almost certainly need a chiropractor from bending over backwards so far to accomodate your wife's irrational behavior and mood-swings. Enough is enough.
Continue to be respectful towards your wife, but be firm now, too. You are headed for some real tough times, but if you proceed with caution, dignity, and good counsel, you and your son will get through this.
Whether you and your wife ever get back together remains to be seen, but the situation is just way too toxic for you and your son to continue in this vein, and, who knows, maybe this will finally be the motivating factor your wife needs to clean up her act and get help for her sick behavior.
I can't remember what you have said about the custody of your son, but given your wife's apparent emotional problems, for his sake, you should seriously consider demanding that you be the primary parent.
I also strongly recommend that you discuss with your attorney being the one to file for divorce and not wait around for your wife to do so.
