Apologies as this is a long one.
My partner has a 6 year old child who lives with him. Him and the mum are divorced because she had an affair and got pregnant with this man’s child. She now lives with her new partner and child over two hours away from her eldest child and has done for 18months. They said they would move back to the area so she could see her eldest more, this is no longer happening. There have been occasions especially before and after new baby was born where she didn’t see her eldest for almost two months. The mum sees the eldest every other weekend and half of the school holidays.
My partner is the primary carer. Even before moving the mum had no involvement in their schooling, hobbies, taking them to friends parties or arranging for them to spend time with grandparents and cousins etc my partner has always done everything. I have been with my partner for a year and also have a child. Our children love spending time together and the children have met our families and it is all working well.
The problem is that the ex doesn’t think that my partner should have him for very long over the holidays as child is always with the dad and that the child should give up swimming lessons and not go to friends parties if it means she misses out on her time with the child. She rings and shouts at my partner in front of his child if she finds out we have all spent time together. Recently this has been because we had a tea party for my mums birthday which we all attended. In addition she rings on a night to speak to her child which is fine but sometimes doesn't make these calls then gets annoyed if she rings the next day and they are out or doing school work etc so are unable to speak to her. They do try to ring back but again may not be able to get through. My partner is again blamed for all of this.
My partner has always allowed the child to be with the mums new partner and his family. Apparently that’s allowed as ‘she is his mother’ but it’s not allowed where me and my family are concerned.
The ex blames everyone for her choices, she blames my ex for the fact she had an affair for over two years and would spend weekends and long periods of time away from her child to spend time with her now partner. She also made the choice to move away but again blames others.
I am sorry for the long post but I am after some advice as to what I can do to help and advise my partner. I feel like we are going around in circles and if we decide to move in together that she will make our lives miserable or take drastic action. The child prefers living with their dad and often when they go to their mums does not want to speak to their mum and cries when they know they have to go to their mums. I feel so helpless for this child as I hate to see them in distress.
