Hi all, I've not posted much on MN so apologies if I'm not up on all the etiquette! I've also named changed for this post. Basically, my Mil's partner has a history of being on sex offenders register. When dh told me about this I was pregnant with our first child. He didn't know all of the details to tell me and I didn't push to know. Mil suggested that her partner never be alone with the grandchildren and if she ever had them overnight at hers that he stays elsewhere. Fast forward a few years, we now have 2 dcs, and her partner is never alone with the dcs and mostly when mil sees them he's not there but sometimes at family gatherings etc he will be. He has a good relationship with his own children and has grandchildren. Recently mil broke it off with him, and dh and I found ourselves feeling massively relieved that we didn't have to have him in our lives again. A few months down the line, they got back together. I found myself wanting to know exactly what had happened in his past, so I told dh to ask mil. The truth is much worse that I'd anticipated, involving systematic abuse of a child over a long period followed by a prison sentence, around 25 years ago. I feel totally appalled and basically don't ever want to see this man again. I certainly don't want my dcs in the same room as him. Aibu to want no further contact? I feel so stupid for not pushing for details sooner, but have no doubt that my dcs have been safe. I just don't want him in our lives at all, and feel way out of my depth with this one. Thanks so much if you've managed to get this far.
