Ds is 12, almost 13. His father left when I was heavily pregnant and drifted in and out of jobs until ds was 2, never really paying any maintenance. I paid for everything ds needed/needs. The CSA assessed him and since he was 2 he's been paying £200 a month (lower then the assessed amount then).
For the first 3 years contact was sporadic. He'd fail to turn up or arrange for ds to spend the night at his mother's so that he could go off and do other things on his contact days. I admit that I didn't make it easy for him when he did this, I'd nag. He moved abroad when ds was 3, saying he was bored. He said he'd come and see ds every few months. He didn't and has seen him 3 or 4 times in 10 years. He keeps saying he'd like ds to go and see him yet makes no effort to contact ds. I don't know how much he earns, he's still paying maintenance though. He got married 6 years ago and they have a daughter who ds has never met. Ds gets no phone calls from his father, he did email for a few months (because I told him to), has sent 1 letter.
The maintenance has never changed, although my finances have. I became ill 2 years ago and had to leave my job. I've become self employed and it's financially hard at the moment. I sent him an email last week asking for an increase in maintenance until I was earning some more money. For the past 2 years I've been paying for ds to see a physio as he has hypermobility syndrome and is unable to walk any further then a few metres without falling over or finding it too painful to walk. My travel costs have soared since he started secondary school as I have to go with him (due to the falling). I need help from his father as ds still needs the weekly physio, which I can't afford.
Tonight I've received a text message saying they have just remortgaged and they had another baby at Christmas. I'm annoyed that he hasn't put our son on his list of priorities, yet again. Ds is suffering and it's selfish of him to have another child when he can't look after the ones he already has. AIBU? I need some perspective here as I'm pissed off!
