My kids Dad is seeing a new women again. He had been on two dates before having her spend the weekend with them. She did go home the first weekend. Two weeks later she spent the weekend with them again but this time she spent the night as well. My son who is 6 said that he slept with them. Of course this upsets me and it is not a jealousy thing. I have been praying for him to find a decent women that would be good and trustworthy around the kids because I know that he isn't. But anyways, I explain to him that this is not OK. First we also have two daughters 9 and 11 and this is sending them the wrong message. And it is just not OK to let he kids sleep with the new girlfriend. Can I legally refuse to let the kids spend the night. I told him that they will not spend the night there again. I have physical legal custody of the kids. This is on the heels of him letting a total stranger (male) stay with them on the weekend the kids were there. He said he came from several states away and was Amish. He would go out to the bar and then come over to the kids Dad house in the middle of the night and spend the night. Yeah, with the kids there. He has taken the kids to this same bar that serves food on Sundays. He drinks over on the bar side leaving the kids in the opposite room. When he is finished he drives them home. He tells the kids that it is OK because he waited a hour before driving. I could go on and on about the things that he has done. I am truly scared for them. What can I do. I can't afford a lawyer and when I call they all want a large amount of money up front. Please help me.
