Basically I have children from previous relationship and son with partner. He has a son from a previous relationship who's almost 11.
He wanted his son to live with us but his ex has said 'over her dead body' but she rarely has him. He basically does live with us and she sees him maybe a couple of days every few weeks if that. She gets all the benefits for him still and I just don't think that's right when she doesn't even have her child. She said she works three days a week but picks up extra hours, we don't even know when, we just don't hear from her.
AIBU to think we should be getting the money for him and my partner needs to grow some balls?
