I have 3 dc, my ex p comes to see them on a Sunday but always stays in my house with them, he lives 1 hour away in a bedsit so not suitable to take children there, whilst I have been ok with this for a while I feel like he shouldn't rely on me so much and take some responsibility in his life. When he is here is absolutely vile to me, I put up with it or the children wouldn't see their father, over the recent months it has slowly dawned on me just how rude, nasty and narcissistic he is and I feel hatred towards him, If I said he couldn't come here and see the children I know he wouldn't make any effort to see them and I feel distraught for my children as they think the world of him, what do I do?
