My ex of 4 years has found out I have a new partner so stopped all contact with out son and also stopped maintenance payments even though its through collect and pay currently. He only seen him on school holidays and in summer did approximately 2 weeks in total and would do 3 days over Christmas or Easter etc. I am devastated for my son, I hate that my ex is using my personal life against him and would hurt him emotionally like this. Does it ever end? I know he didn't exactly have a full time relationship with him but it was still something and now it has stopped all together. I feel a terrible guilt as though I have hurt my son but I know this is not my actions and i don't know what to do.
