I am struggling to co-parent with my ex who abandoned us when our daughter was 16 months old. He upped and left 3 weeks before christmas 2022 and by January I received court papers and had seven months of hell battling through court despite him still having regular contact with our daughter. Communicarion was non-existent for over a year and he got family members involved to try to intimidate me. Despite all this I was still in love with him and struggling massively with all aspects of co parenting and having to see him at handovers. Then this year when I thought I couldnt cope with any more heartbreak my mum lost her battle with cancer. My ex sent flowers when he found out and then we began talking and he said how sorry he was for all that had happened and for me losing my mum. We met up a few times to discuss contact arrangements and we ended up having sex and then the games began again, hot and cold behaviour from him and pushing and pulling as he did during the 3 years we were together. Obviously still grieving my mum I ended contact with him as it was hurting too much. I really do not know how to move forward and am struggling daily, I cannot accept how he has treated me and why he came back to dig the knife in at my lowest point.
