i fully sympathise with you. it sounds like you are having a hard time. I caught my MIL out in a lie but she doesnt know that i know. I have found when you suspect an IL lies or betrays your trust and you finally catch them out with solid proof (whether they know you know or not), it is sooo hard to recover from that. the trust you had is gone. Personally, I have decided in my own situation, and I think you should do the same, is to allow supervised day visits. In time, if she can earn your trust you could start with unsupervised short visits. ur DP will be really torn but ultimately will side with the health and safety of his family.I'm sure she will learn a valuable lesson. She had her kids and did things her way, now its time for her to let her kids do things their way. I'm sure she now knows thatif she doesn't, she risks losing them permanantly.
