When you are in abusive relationship, are you going to stay because of love? Or for your family?
Nowadays, couple or when in relationship and have a child even you are experiencing abuse from partner they just take it. Sometimes they are called martyr. Experiencing hardship in relationship but still choose to stay even though it's hard for them. To break abusive treatment, you need to get away from it. Getting away may not be easy, considering your child feeling is the most important. They needed to avoid traumatic experience that may implicate them.
For me, when the time I experience abuse once, I will not let it happen again. Someone ask me, how about if I have a child. My answer is very simple, me and my partner are the one who will separate, not my partner and my child, not me and my child. We will still provide what a child needs. Physically, financially and emotinally, the child will not feel emptiness. Maybe my perception for now is very narrow because I'm not in this situation yet. But who knows what future brings. Maybe, I just need to be ready and strong.
