Muddle, make sure you see a lawyer before you do anything in re: to separation. The last thing you need is anymore unpleasant surprises! Also, be sure you are OK with this woman caring for your son. When you aren't there, regardless of the amount of time he is with you, he will be with her untended. Just cover the bases for yourself and your son. Do what you must. There are lots of people on this board who are with you. We each have our limits and it appears you have reached yours. No shame in that. Keep us posted.
