Me & ex split up when Dd was 3. She's now 9. At the time he earned around 42K and gave me £280 per month. He's had some promotions since, but told me there were no real pay rises. I never questioned it. He got a big promotion recently, and gave me an extra £45 per month. I asked to see his pay slip cos I had thought for a while he might be underpaying. He said he has no payslip, problems with HR, but gave me some figures on a post it note. Rather than no pay rises, his promotions, before the latest, meant he earned 53K? And he now earns around 63K? AIBU to feel a bit coned?
