I would rather you improve the marriage and make everyone happier, rather than running away and making your son confused and mierable
Anything like that.. the key is to keep the comments to one sentence if you can and to EXIT the convo after you throw it out there.. don't keep batting commentary back and forth like a tennis ball .. you want to come up with a good hard hitting comment and then get out of there.. FIRST... hang up or stop replying...
You don't want to reply with a smart ass comment to everything she ways...
I would suggest you go through a list of things she's thrown at you and practice comming up with one good hard hitting line for each...
You don't want to use them all, but you want to be good at coming up with that one good line whe you need it and quitting the convo...
THat's the one two punch...
Hit them with the truth and then exit the convo/hang up
