I separated 3 years ago, at that time i agreed to continue to support my son (nearly 22) through Uni (4 years in Dublin), which i would have anyway. We got help with the fees, but i paid his living costs and rent. at the time this was €1000 a month, I'm now paying nearly €2000 a month, and am continually being asked for extra, last month it was €400, today another €500, and already warned at least another 300 next month as he need a new passport, and flights to UK, as he need to attend an interview at the passport office?. I've tried to tell her I can't sustain this, and that she needs to contribute, but i get told she can't afford it and this is what I agreed to. I've suggested to her he should get a job, but she says he does not have the time, and it would put too much stress on him in his final year. She has asked me not to mention it to him, as she says he is already doing his best to keep costs down, and it would upset him. This is now nearly half my income every month, but everything I say is ignored. I should also say i gave her a settlement of 75% of everything we had, so she could buy a house in the UK, leaving me in rented while i try to save for a house myself. i suppose i'm just moaning, but any advice is welcome
