Hi I know there are many wonderful and wise posters there are on here and I have learnt a lot on the relationships thread the last few years whilst my marriage fell apart.
I just wondered if this thing that my husband (stbx) does is quite a common thing that people do and wonder how other people deal with it if so.
To put it in context....if we are discussing something and I react in certain way (am not prone to overreacting - just normal I think) then he blows things massively out of proportion about how I reacted to things... and then the conversation/discussion rapidly focuses on my over reaction, my crazy behaviour and me blowing things out of proportion rather than the original issue.
This could happen about anything and did very frequently when we were married ... and it's so infuriating. Just to give an example. DD and DS had their weekend with him - they all visited grandparents about a 5 hour drive away - all good. Ex DH drops them home and says he has left DDs school coat (only warm one) at the grandparents. I was a bit pissed off as its cold this week and wondered what she was going to wear so my reactions was 'oh' (accompanied by pissed off face/tone of voice). He then replied in a really loud sarcastic, aggressive voice 'Yes of course Honinmyo - it's OBVIOUSLY the end of the world isn't it, of dear what ARE we going to do ?' etc etc just trying to wind me up. 
I then get told that I ALWAYS overreact to EVERYTHING , and if I could just stop reacting then we could get on a lot better and would be better for the kids etc. I am normal - I will admit that he can put me down a lot, (will still disregard and disrespect most things I say or do, would never acknowledge that I might be doing a good job with the DCS (2 and 5) and frequently informs me that he 'needs' me to change my plans when he can't do his pick ups, drop offs or take the kids over night because he is moving again etc) so there is a chance that he can sense exasperation in my voice when something else happens on top of all of this but still the point remains... Every single thing becomes focused on how wrong my reaction is and I feel like the thing that he did wrong in the first place (to which I was reacting) is allowed to get completely buried 
He has a strong and confrontational personality (is v insecure underneath) and I dislike face to face discussions with him but I feel like I allow him to control our conversations. You could say that this doesn't matter - we are no longer together even though this was a huge problem in our marriage but bringing up 2 small DCs in a supposed co parenting situation does require a fair bit of communication - not all of which can be done on email (my preferred choice)
I talked to a friend and she said her DH does the same... which made me wonder if it was a common thing in relationships and if so how do people cope ?
