My boyfriend and I have been together 3 years and are expecting a baby this summer. We have a child each from prev relationship and both have additional needs quite the opposite in personality to eachother but we try and make it work. His ex doesn't allow him to be at my home with his child but because she has stalked harrased and abused us we know this is irrational and just a controling trait from her. We therefore do spend weekends together with the kids. She doesn't want to care for her disabled son and seems to want us to have him every opportunity she can. (he spend all of Christmas with me and my family and didn't see his mum for a single day) baring in mind she has another child who is not disbaled that she spent Christmas with. Now she gets paid £3000 a month for this child because of how severe his disabilities are and doesn't work to care for him however every week she is saying my partner needs to have him Friday to Monday which clashes with us working and doesn't work for us. She gets abusive if we say we cannot do this. She now expects us to have him every half term but my issue is that because I work part time to care for my own child with additional needs I only get a certain amount of leave. I can't take off every half term for my own child let alone hers. My partner can take the time off but if he does as I stil have work and my son stil needs to go to childcare setting this wil be very disruptive to his routine in the morning. We have a 2 bedroom bungalow and my partners child sleeps in my bed with his dad and I sleep on the sofa and the space is small. It is very hard for my son in the morning when getting ready for school he struggles with this every day without having another child with additional needs this causes me a lot of stress to because of how worked up he comes. My partners son has limited understanding and will disrupt my son but not on purpose and it causes chaos. I don't want my son going to school or holiday clubs feeling distressed so I have said if my boyfriend has his son he can go to his mum's during the working week. Now my problem is when I am heavily pregnancy during the summer he will not be here with me for 3 weeks of that summer holidays because Hel be with his son from previous relationship. Am I the arsehole for feeling like his mum who doesn't work should be caring for him rather than disrupting our life? I love his son and am happy for him to be at my home and even sleep in my bed every weekend but during working times I can't put my son under that pressure or cause myself stress in pregnancy. I can't help but feel like he's choosing his past life over me and having a new family? I'm not sure if it's reasonable for him to agree to this and leave me every school holidays. Surely his mum should have him? I have suggested we take off the same annual leave for half of the holidays and have the boys at home together to avoid the long process of stress geting them ready for school and myself for work but I unfortunately only get a small amount of annual leave as I only work 16 hours a week.
