Taking the children to meet the new partner.

Just one point though - if contact is the right of the children, then surely it should also be their right to spend some time with their parent on their own - without the new partner butting in all the time?

I would say give it time, just continue to see them as often as you can, i was at age 10 when my mum brought NP home and believe me it was outright hostility from me at first sight, as ive already siad a couple of times, it came to throwing water over them. salt in the drink. dinner, what ever till he left, the same happend again on next NP and so on, oh I took a few thumps and made things even worse for them by bringing the police into it, do i regret it now, do I hell, though my thoughts do go out to her with having no one over those years I stayed at home, she is of course now married again and we all think hes a nob, but if my mums happy then so be it.
