sounds like a fantastic solution but it was very hard at first moving from Aus to the UK knowing no one. Luckily I had a job..... I never in my widlest dreams expected to be returning to Aus four years later with child and husband in tow.
It really does get better - just a little each day. The other thing that made me feel good was that for the ex-best friend - if he cheated on me- there is the possibility that he would do it again.... I don't have to live with that worry.
Sadly - as you said your deepest fear - about him not realising what he has done- it seems he has a lot of growing up to do before he gets to that point and sadly - some people never get to that point - being responsible for their own actions.
As to his comment about change the unlovable - that is a statement from someone who has no idea. Obviously to him ( the perfect lovable person .. imagine sarcastic tome)that is a simple solution - you change cause that again means he does not have to face that he has done something wrong and accept the consequences for his actions...... as with my exdh - it was all my fault he had an affair the whole time we were married and ran of with ex best friend - probably still is 12 years later ( still my fault that is). When I looked back on it - I realised he was like that - everything was always someone else's fault - then I looked further and his father was like that - it was always someone else's fault..... never ever were they in the wrong or had they caused anything. I am just so glad I am ou of that situation.
I want to wish you well and say you are very brave. It really does get a little better each day.... you are a strong woman who is making a difference in your children's lives.
To be honest - I would not waste any more energy on him and the little girly. Focus on your kids and yourself - a much better use of your time and energy. ( although - i appreciate- for you this is much easier said than done at this point in time)
But remember - you are woman and you have the power - that is why ex and girly are behaving like that. If they too had moved on then the focus for ex would be on his children and not you.
Hope you are enjoying those flowers.....
Sorry to ramble on - will stop now.
