Backstory - he left 1.5 years ago when our child was 2, immediately moved in with new woman, sold our house and I moved in with parents. They got engaged 6 months later.
Yesterday I found out he’s having a baby with the woman. How do I stop this taking up so much space in my head? I feel like I haven’t even processed him suddenly leaving and losing all my in laws and my home let alone everything that’s happened since. I was with him for 15 years and never imagined he would replace me like this. He literally doesn’t care.
How do I get over this? I still have to communicate with him for our child.
