So the brief story is . Partner has two kids , her ex contributes nothing financially or with childcare.
Every 12 weeks he would have one over night on his terms when he clicked his fingers combined with messaging my partner randomly asking if they were ok or for when he needed a favour.
As things progressed I told my partner I don’t feel comfortable with this and I want her to claim child maintenance off him and force him to share child care . She refused .
I have since moved in and I am going to split bills etc whilst he pays nothing and has to be forced into the odd weekend of child care .
I feel my partner could do better than simply accept this arrangement am I being unfair ?
