the only thing this kind of people want is to scare you, so they can control you.
those people need to control their partner and if they can't control you, they'll find an easier victim.
From my experience this is true. My exbpdh managed to control me quite successfully for a while as my kids were young and I relied on him financially and didn't have the freedom to go out much. He also controlled my kids, (by using physical violence, as I later found out). The problems really started when my son became older and bigger. My ex suddenly had a real thing against my son and blamed him for every little problem we had. He even looked for faults and took any opportunity to have a go at my son. Eventually he went too far and the police became involved after he beat my son. This was when we separated.
At this point my ex just found somebody else. Even though I was stupid enough to believe we could still work things out, he just replaced me without a second thought. Strangely, (or maybe predictably) he has replaced me with a woman who will be very reliant on him financially. She has also moved from her own country to be with him so she is now very dependent on him. She also comes from a culture where women are very much second class to men and are often physically abused by their husbands.
I think he is probably over the moon to have found a woman like this!
