Bit of background - I separated from exh in May this year - there was no one reason for it, just had come to the end of the road, imo. He asked for a trial separation, and I agreed, but told him that I didn't think a 'trial' worked - we should separate for good. A couple of days later, he asked to try again, and I refused. So we have been apart ever since.
He sees lots of ds - a couple of overnights a week and almost every day either before or after school. I also have a dd from a previous relationship, that he has not spoken a word to since the day he left 
The problem is this - he talks to me like crap - looks at me like I'm something on the bottom of this shoe - generally as if I'm being punished..... for what? I really wanted to stay friends for the sake of ds, but it's becoming increasingly difficult not to rise to this - I am never anything but reasonable and cordial towards him, and I don't deserve this treatment. Plus it makes me really fucking angry
Do I confront it, and let my calm exterior sink into screaming fishwife mode? Or just carry on with the ignore, ignore, ignore thing that I have been doing...?
WWYD?
