I feel like I’m banging my head against a brick wall. Trying to discuss maintenance for children over the weekend. What he’s offering monthly is insulting to be honest. Obviously I can’t put in figures here but its very low. I’m not skilled at debating like he is. Trying to avoid mediation/ solicitors etc…but I can’t allow myself to be a doormat anymore as it isn’t even about my. Any tips advice to deal with this?
