TLDR: W wanted to separate after 17 years together from 16 years old and 2 children. Was very cold and distant, started staying away in hotels for 3 weeks each night leaving me with the kids. I moved out thinking we were just separating. After guidance on these boards it became apparent that she was in an A. I bugged the house and it all came out, she was having an A with one of the kids dads who she childminded for. They planned the whole thing, he is 14 years older, his second W is pregnant and he has two kids from his first W. I exposed the affair and his W got rid of her house and he moved in with my W and kids. I tried to confront her about the kids being around him and she had me arrested. Since then its been one thing after another. Rest of detail is in part 1.
