Hello MN, I am in need of some advice regarding my kid's SM...I won't waffle on about our circumstances but to say that I have 3 children with my ex and we divorced 6 years ago & have both remarried. My son was staying at his Dads a few weeks ago and whilst on a day out with his SM dropped his phone & broke it, it was an accident and he was very upset (he is 12). His SM called me to say what had happened and I said not to worry just send it back & I'll get it fixed when I can, tbh I'm not in the financial position to afford it at the moment, anyway his SM decided to get it repaired anyway which she sent me a message to inform of this. A few days later my ex called to say that he felt it was unreasonable to expect her to pay for this and could we go halves on the repair to pay her back. I did't really agree either way I just sent back a message saying that she did it without my agreement and that we'll discuss another time. He felt that was unreasonable and said that she is absolutely not responsible for that cost (£120) and that could we please come to an arrangement to reimburse her....my issue is that I did not make an agreement to pay her back or for the repair to be carried out, my ex says that she was worried that my son wouldn't have a usable phone so that's why she did it but I then feel that as she made that decision she took responsibility for the cost... I'm not sure whether to be firm about that or whether I am being unreasonable about it???
