Thanks Sandi, for your advice and infinite patience.
Yes when my PMA is not good I start worrying whether I'm standing reasonable ground or being sulky. I get worried about tone posture and all the rest. My confidence is shot to bits on these issues.
So point taken sort the PMA and the rest will follow.
The dress was a conversation slightly before the talking accross. The kids had photos at nursery today and I took then. My W said that she wanted a very specific dress. I said that I didn't really like that dress but since it seemed important to her then I was OK with it. She started to try and tell me why it had to be that dress. And I stopped her by saying I had a right to an opinion and that I'd already agreed to what she wanted. Maybe it was b*****y it certainly pressed some of my buttons and I felt myself starting to rise to it.
I think it still confuses me about how to behave - I think I'm just being impatient about it all. I think the advice I'd give is to hold to my boundaries but otherwise perfectly friendly and interested. Resoect her privacy and space. No relationship talk. But otherwise as natural as I can manage. If my PMA is poor then excuse myself - no interaction better than bad interaction.
Pause for thought overall - something to make her question leaving the M.
