ex-wife

Q: I divorced my wife 3 times not in 1 go. We are living in the same house as we have an 8 year old son. Me and my ex wife dont see each other in the house. If she is upstairs I am downstairs and vice versa. Its a rented property. She has said after her iddah she wil move out. Is it ok that we are living in the same house? Will we be sinful? Our son is becoming a hafiz so thats why I have not moved out from here as I wake him up in the morning and sit with him whilst he prays. He is used to being with me. He doesnt learn properly with his mum.

Q: The presidant of a masjid is living with his ex wife after divorce. We feel that this is against the teaching of Islam and therefore detrimental to the image of the masjid. Please advice?

Q: I am very stressed just wanted to know mufti. You the only person I know who can tell me what is right and what is wrong Islamicly. My husband is continuously communicating with his X wife and he hides what they discuss. When I ask, he says we are talking about the children and yet the last born of their kids is almost 25 years of age. So all four kids are big enough to come or call their father and talk to him themselves so why should he still talk to his X yet he told me I am not allowed to communicate with my X and ever since I do not talk to him but he says he needs to speak to his X. It hurts Mufti. I feel like I am nothing. What can I do?
