You say 10 days of "relative peace", but also that she's snapped at you many times. Doesn't sound peaceful.

I'm not sure other than to avoid being in a vehicle with her. Maybe others have thoughts.

Good job.

It's incredibly common around here for the WAS/WS to blame the LBS for the WAS/WS's actions. Remember, for your own sanity, a persons' actions are a reflection of their own character, not yours.

I'd believe her when she says she's confused, but remember to trust her actions not her words.

She's going to seek out justification & validation for her actions & decisions.

Also incredibly common.

There's no excuse for this behavior. You can not condone or allow her to scream and swear at you in front of your child.

It sounds like she has absolutely no respect for you. That's ugly behavior.

Good.

Thoughts and advice?
No idea what the messages say, but you're smart for focusing on your son and waiting. I wouldn't respond emotionally, IF at all. Unless there's a critical item about your son, it's unlikely you need to / should respond.

How should I respond to a question like this?
It sounds like she's trying to be ugly and mean to get a rise out of you and make you be the bad guy / pull the trigger. You don't need to respond at all. However, if you have to say something "I'll have to think about that.", then leave the room.

PeterB - That's a lot of anger and hate sent your way. Hang in there.
