Hi Liam, i hope you don't mind me posting on your thread. I've been on here about 4 years and been through some of your pain. I'm out the other side and just wanted to give some encouragement. I was 25 years with my exw so i have some idea of your experiance.
I've read through your posts and you are doing well with the c@ap you are having to face. The advice you have got on heae is invaluable and you seem to grasp that your W is not who she was and you need to keep contact to an absolute minimum for the time being.
As others have said , your children need to see a dad that puts them first and be their rock. Also this is a time for you to become the best you possible.
It will feel like this pain wont end but it will. Whatever the outcome you will be happy again. Easy for me to post but it's true. I didnt believe people when i was told this but i can honestly say im happy now.
What worked for me was letting go of any expectations and moving forward. I was lucky enough to get my 4 kids to live with me 24/7 and i dont entertain any comms from my W unless it relates to the kids. Also regarding the inlaws , i keep in touch but never mention EXW and they know not to mention her to me.
You have complete control of you and you alone, make good choices based on facts and not feelings. Stay calm with any dealings with W and be prepared to walk away if it gets heated. Always take the high road and act from the best you even if that doesn't feel 'good' because you want to be able to look back on this time without regret on how you acted.
