My [F/30] husband [M/31] of 7 years wants to involve his father, who is a registered sex offender, to be involved in our and children's lives - am I wrong in not wanting my FIL anywhere near me or my children?

Posted this in r/Relationships originally but mods suggested I post it over here instead;I can't believe I'm even having to write this. My father-in-law [72] was convicted of sexual battery around 13 years ago and was released early 5 years ago when my first child was turning 1. To my knowledge, my husband hadn't spoken to his father since he was arrested and never seemed interested in the idea. We met only about a few months after the arrest, and he had already cut off contact by then.About a month ago, my husband mentioned that he'd spoken to his dad recently because his older brother is getting married in December. And then a week ago, he asked how I felt about inviting his father to Thanksgiving. I was appalled. Even though his father didn't assault a minor, I'm really not comfortable with him being around our children, especially since I haven't even met him.I told my husband absolutely not, and he seemed really upset. He wants to give his father another chance, but I can't get past it. I feel bad because my husband genuinely seems to believe that his dad's changed, and while that might be true, he's still a registered sex offender, and the details of the crime aren't pleasant. Am I being paranoid? Should I agree to Thanksgiving with my father-in-law and involve him in our and our children's lives?TL;DR: My husband wants his estranged dad, who is a registered sex offender, to come to Thanksgiving, but I don't feel comfortable having him around me or my kids. via /r/Parenting http://ift.tt/2xqEywF
