If its just a matter of responding to texts keep them short and don't stray from the subject. I have been making this mistake of going off on a different tangent really going into detail, when my response (if i'd have taken 5 min to think about it) could have been a few lines long!
If you mean comm when your face to face, this is entirely different! When I pick kids up I show her I'm up beat and positive, I always look my best, I keep things short and don't give her the impression I'm waiting for her to say something about the M. The kids are a great distraction as well and can keep your mind of off talking to W. I'm going thru exactly the same thing and don't get me wrong the above sounds good but your insides are in bits, I know!
As with all the advice we have read on here, keep to the point and validate and understand what she is saying while keeping eye contact.
