Years ago under a different UN.
We are a blended family and had DH daughter 80 percent of the week and his ex had her 20( So we had her mon/Friday, ex had her Sat and sun) This was court agreed and what ex wife asked for.
Every weekend on a Friday exwife would state she had made plans to go out on Saturday so DSD needed to stay here. This got to be so regular that in the end DSD only saw her mum on Sunday about twice a month.
We didn't mind at all and loved her to bits, but it did make DSD sad and she needed some therapy.
We obviously covered all DSD costs, clothes, school uniform, trips, school supplies, hair/makeup ect( DSD was a teenager). Mum never paid a penny and although we would have been entitled to CM from her, we never asked for the sake of harmony as poor DSD was already sad enough.
When it came to DSD prom, we were in a very difficult position financially for various reasons and asked ex if she could help towards costs. She refused and I had to sell my ring so we could afford DSD dress.I was sad, but when you love your kids you make sacrifices for them and I didn't want DSD missing out.
When I posted about this the backlash was HUGE. My DH was a downbeat dad who needed to work more( Even though i had stated he was working 2 jobs to try and keep us all afloat) . Who did I think I was taking over the mothers role? It wasn't possible that the ex didn't want to see her daughter and I was making that up. My personal favourite though was even though we had DSD pretty much 100 percent of the time, WE should be paying the ex wife maintenance, and to be thoroughly ashamed to ask for any kind of contribution from her!!
The sad thing is, take a look at pretty much any stepmother post and you will see insane stuff like this.
