Me and his mother are not together since his birth. From the age of 2.5yo he was always upset when time to go back to her came . At this moment he spends with me 4 out of 7 nights and during school breaks or summer holiday he is with me 6 out of 7. Every week when I drop him off at school on her day to pick him up after he gets upset and doesn’t want to go. Teachers are aware of this, but say they cannot do anything. I spoke to his mother about it but she refuses to acknowledge his distress. My son is asking me to pick him up on her day just to reduce time with her. I can’t watch him upset every single week . At the same time I don’t want to go there and make her start to pull or drag him causing scene . I don’t want police to come and see me as the bad guy and further use this against me. We don’t have court order, so my lawyer said it’s nothing to do with police anyway. I don’t want to go court because if they side with the mother I will get 50/50 and my son is going to be even more distressed. She is very selfish ,indifferent towards him ,depressive and immature attention seeking. Years ago she would take his toy away and just watch him upset. When I addressed this the next day she would call my phone and put hers on loud speaker so I can hear his screaming because she done it again. At that time I didn’t put things together and didn’t know it was done to make me upset. So yes attention seeking , causing distress in others to regulate own self esteem. Another time she would leave for work without underwear saying that she gets thrills knowing other men at work don’t know how easy it is to get access to her vagina etc. I’m actually embarrassed now saying all this. That’s my sons mother! What can I do? I’m sure if the table was turned and child didn’t want to go with father school would sort this out. Because it’s her I think everyone ignores and refuses to help. Any advice apart from going to lawyers and let myself go broke?
