From 2003 to my interim order in 2005 I received nothing from my ex in terms of CS, SS, or S7s. From 2005 to 2013 when I got my final order he paid symbolically sometimes. I now get CS and an averaged out amount for S7s thru FRO.
Throughout the ex made ok money working the job he continues to hold today. Much of this time I had zero employment income, staying home to care for my youngest child who is special needs and put myself thru college to supplement my university degree so I could get a decent job when my youngest started school full time (I am now employed).
Yes, I paid daycare exclusively for three-ish years (even when care was fully subsidized but I needed ex to provide mortgage statements for the mat home to prove eligibility... Which he didn't), for braces, for various therapies, etc. Do I think it was/is "right"? No, but that is what you do as a parent. You provide for you kid(s).
My focus is and always will be moving forward, that is what matters, not complaining or bashing the ex. Not an ideal solution, what I have done is to work S7 into my payment from FRO. Work out the average S7 expenses over a year, divide it by 12 months, and add that amount to your payment and be grateful that you are getting some contribution. The trouble I have now is how to keep this calculation up-to-date and how to ensure ex submits health claim forms when I try to coordinate benefits.
If anyone else can offer a better solution that has worked for them I'm all ears.
