I’m so sorry 😔 it’s absolutely soul destroying when they become someone you don’t know at all overnight and you can drive yourself mad trying to get answers from them but it’s waste of time because you never get any that make any sense. They’re just a totally different person now and best to let them go off into their little fantasy life (it never quite works out that way for them after time )
It’s difficult when you have kids with them because you have to try and be civil for their sake when that’s the last thing you want to be with them - it’s three years on for me and I still refuse to be in the same room as him or talk to him on the phone, text messages only - which he thinks is incredibly petty of me but I can’t help the way I feel.
He said he wanted to stay friends and I really felt pressured to do that for the sake of our kids but it was a huge mistake because it only confused them even more imo. If I could give any advice to you it would be don’t fall into that trap - but of course there will be some people it’s worked well for them (I don’t see how lol)
You just have to take each day as it comes for now and know that that horrible pain you feel in your chest will ease off eventually and you can enjoy your life with your beautiful little girl and one day you’ll realise you are so much better off.
