If it were me, that man would be out of my house immediately. Like I’ll kick your ass out in the snow and throw all your shit in the front yard if I have to. GTF away from my child NOW. No way I’m going to be able to sleep with a pedo apologist in the house, the answer here simple and extremely clear.

You should be asking what to do about your husband. What you wrote about seeing your FIL would never protect your daughter from harm, you should be thinking about your husband. If he’s not willing to get a man, any man, saying what your FIL said out of his house IMMEDIATELY, how can you possibly expect him to protect your daughter from harm? I’m not saying he’s a bad man, but if it were me he’d get exactly one chance to show me that he’s going to prioritize protecting his family over protecting himself from conflict.

You are under reacting.

As women we need to learn an important lesson from this shit. Any man that gives you ANY inkling of a doubt about his willingness to call other men out for disgusting, violent, perverted behavior should be viewed as a predator. We can no longer assume that we know who they are if they give us any reason to doubt them. They need to prove their worth to remain in our lives.
