I really need help. I am 24 year old and my ex girlfriend had our son 18 months ago. The month before my son was born she said she was moving back home with her parents so she will be close to hospital. I agreed with this as a supportive boyfriend. The day my son was born her mum called me late so I did not get to see his arrival. I travelled 3 hours to hospital and she started a fight and kicked me out. Ever since that day, I have only ever spent the night with my son when his mother decides to use me for a weekend holiday away or a week holiday which I pay for as she gave me false hope of being a family. She did this at least 6 times over the 18 months. Then I find out she never told her parents she was spending time with me. One time we spent a week together with my son and she went home. I did not hear anything for a couple of days. I was texting her and calling her. Then I got my mum too because we were so concerned she had been in an accident. Day 8 she calls me and abuses me saying she had gone on a cruise and did not want me to know because she left my son with her parents. This goes on and on. Any time I ask if I can see my son, she makes me go to her parents' house and sit and play while her family are around. I just want to see my son. It has now been 3 months since I have seen him. She has now put an AVO on me the police just turned up and I could not defend myself. I just took it on the chin. But last week she got the police to arrest me as she friended me on snapchat and was talking away to me. Then she said 'you do know you are going against the avo'. I said "you started talking to me". She took pictures of the snapchat. The police came and arrested me. I am now on a 12 month good behaviour bond. I can not contact her. Only through my nanna. But my ex won't reply now to my nanna re me seeing my son. Please what can I do under family law? I just want to see my son.
