Broke up over my child- is it a good decision?

I broke up with my ex of two years because of issues involving my child. He was a stepfather to my kids, and like in any relationship, we had some arguments. The main issue, though, is that my youngest child can be very stubborn and doesn’t listen, even when we ask her to stop doing something. For example, she would make noises that really bothered us when she was angry or frustrated. This has been going on for a few months.

I told him to ignore her and not to scold her when she wouldn’t stop but it seemed to make things worse when he didn’t ignore her and keep scold her.

Then, yesterday, I needed to hop in the shower before we went out shopping. She did it again. I told her to stop, then went to take a shower. Meanwhile, her stepfather kept telling her off, lost his temper, and even shook the armchair she was sitting on to scare her into quieting down. He didn’t mention this to me until later, when I was getting dressed after the shower. My older daughter told me what actually happened.

At that point, I told him to pack his things and leave my house.

Now, I’m wondering if I made the right decision. My mom and sister are against me going back to him because they think he was controlling and abusive toward my kids, even though we are firm with them and make sure they stick to a routine. On the other hand, my mom doesn’t have any rules for my younger siblings and lets them do whatever they want.

I don’t know if I made the right choice. My kids miss him.
