I need some advice. I have 2 children myself with my husband aged 1 and 4. I also have a stepson who is 11.
My husband and I met as we both work at the same company. We both earnt £48,000 a year equalling £96,000 between us. Stepson stays 3 nights a week Thursday to Sunday every week and we have always paid maintenance of £325 a month. This is over what we need to pay but we looked at what we could afford as a family. We both work full time from home but our jobs do include a bit of travelling, both our parents help when this is the case. This means we have no extra childcare costs.
Whilst I was on maternity leave both my husband and I went for the same promotion at work. This promotion came with a large salary increase and a company car to £94,000. This brought household income to £142,000 a year. My stepson heard us talking about it when he was supposed to be asleep and he excitedly told his mum that I'd got a new job when she picked him up at the weekend. It was not done in a malicious way he was excited as we had talked about going on a big holiday in the summer as a congratulations to me and to celebrate.
My partners ex when she got home sent a message asking what my new wage would be so she could recalculate maintenance. She has said its unfair for her son to miss out on family money. Am I being unreasonable to say no? We already pay her really well, and go above and beyond with my stepson as we are the only ones who take him on holiday and have him every weekend. We also pay for his swimming lessons and his boxing classes which he attends when he is at his mums. She has also told us that she can't get a job as she would have to pay for childcare as she wouldn't be able to get a stay at home job like us.
