Ex has turned something silly in to a petty competition.
He doesn't/isn't supporting the children financially (so I'm going through the CMS) so he does have more 'spare funds' than I do, especially as I've had to claim Universal credit.
One of the children mentioned to him that I planned on getting something replaced, just for him to turn around to me and say 'I bet I get one before you'.
I know he will, but am I petty to be a little bit annoyed that this will be the case? I know I'm going to get flamed for this, I'm sure I'll be told to grow up etc but I'm annoyed that not only am I responsible for 100% of the childrens care & meeting their needs in every way possible but also because this doesn't leave much room for other 'essentials' & knowing he has all this spare money because he isn't having to buy clothes, shoes, nappies etc stings!
