What's all this about you miss your little boy?
Don't you have access to see him?
It doesn't matter wether your an ex-offender or anything, you have served your time and in the eyes of the law your debt to society has been paid in full.
You have your own flat and due to this in the eyes of the law you are self sufficient.
It is unlawfull for anyone to discriminate against you because of this prison sentence, and if your ex is stopping you from seeing your little boy, call social services, they will contact your ex and threaten her with court action unless she agrees to "visits" for you to see him.
The only way she could stop you from seeing your son is if she could prove that you have been violent towards him or are a drug addict or an alcoholic, even then visits are almost always granted under supervision, with the exception of violence towards him.
You can believe this as I am a barrister for the Crown Court
