Ex husband behaviour

[Mummy1679]

Been divorced three years but up until now have kept good relationship for kids. He has them two nights in week and every other Sunday for the day. Go to school stuff together , will get together for children’s birthdays etc.
He doesn’t pay any CM or contribute anything for the children at all as he claims he has too much debt to pay off. Runs own business so CSA useless. I work full time so am managing but it can be a struggle.
But in last week or so his attitude has changed and he is becoming very aggressive towards me saying he has issues about the way I am looking after the kids - for example - wearing (in his words) cheap clothes and hand me downs. Says his family are beginning to comment on what they look like. I get most of their clothes from Asda or Primark!
He is now demanding that things are done on his terms and he wants separate parents evenings and to go to assemblies by himself.
If this is the way he wants to go AIBU to bring up money and maintenance again??
Or am I going to make things worse for the children?

Just to answer this bit, your ex has made things worse for the children by saying what he has and paying nothing. You could certainly keep putting up with his lack of support for a quiet life, but he is then learning that he can do unreasonable things and you'll say nothing. It's hard, it didn't have to be, but he's chosen this route not you.

To another PP who asked about facilitating access even though he pays nothing, kids should never be penalised for having a relationship with their parents based on the financial contribution of that parent.

There seems to be a distinct lack of pride in some fathers paying for their children. It instead becomes about punishing the mother for whatever reason rather than thinking about the kids needs.
