hi, i have a 4 year old little boy, me and his father have been seperated for almost 3 years, he had regular contact with his dad until recent. my son has been telling me he no longer wants to see his dad but does not give an explaination why, and has been waking up crying telling me he doesnt want to see daddy anymore. i have stopped contact for the time being as my ex drinks and smokes alot too and worried this is happening around my child and he has also been giving me a lot of grief of late, being verbally abussive and threatening my friends, he also tries to start an argument even if my child is present, what do i do?
