Been on my own for over 10 years now - the DCs see their dad every other weekend. When they were born he said multiple times how he wanted to be a 'participative father'. He now pays bare minimum maintenance (but has just returned from a 2 week holiday in Dubai), has switched off from my DS's mental health issues, meaning I have to do all DS's related appointments and does not ask how DCs are when they're not with him. Is this normal? Is it better for him not to be involved day to day? I still can't get my head round it
