Tay,
I think everyone here is right - it is very likely escalate.
Hang in there - try to maintain NC if you can.
Do you think it would help to set a short-term goal for yourself? Maybe say - ok 1 week (or 1 month) or whatever you think is workable. Make a commitment to yourself that you will give that time to you and M only – you both so deserve that time. Think of it as giving yourself a vacation from your Mother. Promise yourself not to think about her at all. Everytime a thought creeps in – shut it down. Set the time limit, when the time is up, reassess and set another time limit for yourself....
When I went NC it was really hard at first. It helped me to think of NC in short time intervals. I allowed myself the break, and then would allow myself another break…. It has been about a year now - and it has been the most peaceful time in my life - it gets easier with time. And, IMO, you and M really need this time for each of you as individuals and together as a family.

This made me very angry. It takes a lot to make me angry – but this, oh yes, this did it. IMO, this is a boundary that NO ONE, absolutely NO ONE has a right to cross. This is an epitaph moment. She just tried to drive a wedge between you and your son by speaking badly of you to him. No one, but no one, tries to drive a wedge between my child and me – or vice versa. Nope. That, for me, would be the absolute deal breaker. This can seriously harm a child’s mental well being – they don’t have the wherewithal at that age to understand, and this is the type of action that can haunt for a lifetime.
OOhhhh - She just stepped way over a line that you do not cross with me.
I am so sorry if this sounds harsh Tay. Your mom reminds me a lot of mine (that ugly, manipulative behavior) - she really triggers me.
I am sending you so much strength and many, many hugs – hang in there. I have been there – it does get easier with time.
