My sister went through a lot of stuff like this with her ex-husband. For example, he waited until she went out for an evening and then brought the kids by at 11pm and said he was called into work. 30 minutes later the police show up and start asking her if she had been drinking. She had to go to family court and try to clear her name. The judge asked her why she said yes to taking care of the children when she knew she had alcohol. The whole thing was horrendous. Honestly, abusive men (and some women of course too) know that even a little lawfare goes a long way toward destroying people's lives. It's sick and wrong.
