Thanks BG. I think I get what you are saying. I might re-read it again tomorrow when I'm not sleepy though

Is there a reason your DH is paying for the "extras" (apart from being a nice guy?)
We've been paying the "extras" because we figured it was our obligation seeing as we had the larger percentage of care. Although up until 3 1/2 years ago the kids were with their Mum more (before they chose to live with us primarily) and we still went "halvies" with everything because she always asked. We basically paid out of fear that if we didn't she would turn around and try to reduce the amount we had the kids so she would get more cs from us (she's that type of person...). With them being older and making their own choices now we no longer have that fear
