And that's one of the reasons, I prefer emails or texts vs. phone calls. If he had emailed you that, you could/would have just ignored it. Gives you time to think of a response. And he would prob. have been less likely to make those kind of comments to you in the first place...
I try to do everything through e-mail as well. Mostly because it creates a record. My X is notorious for forgetting things we did agree on and trying to tell me I agreed to things I didn't. If he says I agreed I ask to see it in writing! Unless he has it in writing, no agreement!!!! And in your case Mishka, Karen is right, if you are answering in an e-mail it gives you time to think before responding!!!!!
