I've just moved into the new house I bought for myself and my son. Before, for a year, my ex was coming after work from fri-sun and staying in my rented flat. Every time I told him that he is spending evening with me not really time with his son. And I don't want that. He always responded : I work most weekends I don't have a chance to see my son. I couldn't do anything because he was on the tenancy and I didn't want to sign a new contract. Now the house is mine and my son is living with me. My ex already said yesterday he will be coming every weekend , and I should give him the key as well. By the way, he is living with his parent. Now , what should I do, mediation? Or letter from solicitor saying I'm definitely not agreeing on him coming, I want him to take our son every 2nd weekend to his parents etc. I really don't want him here !!! What if he can't take him, he works almost every weekend? I will never agree on him living with me over weekends.
