I don't wanna consider this situation as love because this is brutally hurting your friend. She needs to open her eyes especially that they have a newborn baby, if she's being practical she should get away and run away go to the police and I think there is a certain department which can help her start all over little by little.
Here in the Philippines, we have DSWD who helped and protect Mother and child who is in this situation and we also have Gabriella Movement. I wish that this incident won't happen again but for her safety, she has to move on as early as of now.
