I didn't intend to come across as smug, but I can see why it might have done. It was just ridiculous at the time that instead of talking to us and finding out that dh was paying over the odds and hadn't asked for a reassessment when he could have done, she just went straight back to the CSA. I believe that it was done out of spite rather than needing more money - because all she had to do was ask.
We have always made it clear to her that we will help out and buy things for dsd in addition to the maintenance. But at the time it was impossible for us to know anything what was needed - she refused to speak to dh and told him that her life and what happened when dsd was with her was nothing to do with him.
If we bought clothes and things for dsd we were either "trying to buy her" or "trying to make a point". There was just no pleasing her and no talking to her.
But now that things are better we pay for loads for dsd - school trips (the week away for £300 type), uniform, clothes, pocket money, out of school activities and I even GAVE her mum my car when hers was stolen so she could still get to work.
Is it fair that we have 2 incomes and she has 1? I'm not sure fair is the right word, it's just how things panned out after she ended the relationship with dh to be with someone else. Her relationship didn't last, dh went on to meet me. She has made her life choices, mine are very different - and that's fine, but I'm not going to fund her life choices. Her household is complicated in that there are 4 dads who should be paying (soon to be 5). I suspect dh is the only one who actually is. We couldn't support a family of 6 as well as our own, nor should we.
