I left my partner 2 years ago when my son was 4 years old, his dad saw him as and when, always said too busy with work, i get minimal maintenance. When my ex does pick him up he always smells of alcohol and appears drunk to which i say he cannot take him, especially as he is driving. Recently he has a new girlfriend who he has only known for 3 weeks and my son was due to go on an overnight stay but i stopped this because my son did not know this person and to be honest how can my ex know her. My partner says what he does in his house with his son is his business and not mine, need to mention my son is autistic, but i pointed out that when he has slept over before my son always ends up in his dads bed and i asked what would happen if he wanted to do that again, he replied well i’ll let him come into bed. My son also comes back from his dads saying that he calls me names and his half sister who is 21 slags me off as well, my son says he doesn’t want to see him, can i stop him going.
