Hi always
Have just read your thread.
I'm guessing you're in the UK like me( I'm in the South).
Your H clearly has his head in a very strange place at the mo. That crazy fantasy world where you can find it so easy to justify any appalling behaviour. You're doing a good plan A keep doing it. The more she tells him she doesn't like him visiting you the more she is LBing him. Just keep on filling that love bank - he still cares.
I really feel for you, there is nothing more unbearable than watching our children suffer. I know it's hard to consider but remember not only are they missing daddy but mummy too. I know my own kids reflect my moods when I'm down. My DS3 would spend all day for nearly 7weeks sat on my lap playing with my hair when i was down. As soon as I started taking more action again and lifted my self he improved loads.
I know you didn't cause the pain (I did and I had my own guilt to motivate me to lift myself). Do you have friends and family to support you too? are you having counselling? I went to Relate with my H before my A was over ( didn't discuss the A) and it was a waste. We have made billions more progress since using this site.
So you've been doing a great plan A. And you know that H is lying to OW - there is hope.
I reckon he's feeling guilty and rubbish about himself and so to make himself feel better is lashing out at you and being grumpy.
Does he realise now that it is his selfish behaviour that is causing the kids to be unsettled?
You have the 13th April to look forward to, can you get in any other dates before then?
