About not allowing every Tom,Dick,Harry,Sally,and Josie into my children's lives?

[Lolek]

My children's mother had 12 children,when they were born,we broke up,when they were 2,she left them.Simply because I refused to take care of all her other past mishaps.She went back to the father of her oldest children,her now common law husband and is saying now,10 years later she won't see ours',because I told she cannot bring all of her other MOSTLY ADULT children along and I told her if she dared to say her children are our children's brothers and sisters that would be her first and LAST visit.All her sons except our son together is grown,they could be pedophiles or her daughters might turn our girls into tramps!She swears her brood is gong ho to meet our children,but I won't allow it.Legally there is nothing she can do,I have sole custody,plus we live abroad.It just seems selfish,she's basing seeing the children she says are her's,though she has never even called on their birthday,on a bunch of grown people,who probably think my children are redheaded stepchildren!What message does that send to my children?"Well,I gave birth to you 3,but Those 12 were already here,so I chose them?"
