To be livid my Ex has bought son XBox but skipped maintenance?

[Biglittlefeet]

I'm a little sick of my Ex!

He has just bought our 14 year old son an XBox but skipped this months maintenance! I almost want to say to our son that he is not allowed it in this house, it can stay at his Dads.

Ex is saying that missed maintenance is because
a) I moved away (12 years ago to be near family) and he had to do the travelling this once.
B) that he has him for a total of some weeks in the year and so does not need to always pay maintenance.

We obviously should have had a more formal agreement. I need to do something, however I know a CSA calculation would be less than he's paying now as he is self employed and doesn't bother to declare half of his stuff.

I'm also sick of paying for his travel. Maybe it's because I moved but I foolishly felt too responsible for everything, and had paid 95% of all travel costs. Which are never enough and he's been telling our son for years how awful it is that he hardly sees him, or that he's broke, and then changes most arrangements last minute and blames me for being 'difficult' if I say please stick to the agreement.

And to top it all my son now thinks I am difficult towards his Dad too.

Ex also says unless I fork out for travel expenses maintenance will be reduced/stopped at any point. Grrr.....

What's the difference between the CSA figure and his normal maintenance and how much is the fare?

I think you need this on a formal basis OP. Otherwise he'll always hold the threat of changing or not paying over your head.

I don't know CSA for sure, but guess it's half. Fares are £70 return.

I wish there was some process which stopped him from being difficult!
