It gets worse. It is as if the two of you go into a silent agreement that if the last bit of hitting was acceptable to you, he has permission to up it a bit next time. This scenario plays itself out all over the world with sickening regularity.
If nothing else makes you see disaster looming, let me paint the picture what these type of men do once you have children. The children become their weapons to hurt you, to get to you. They will threaten you that if you leave them, you will never see your children again. If you manage to leave anyway, they will use the children at every opportunity to get back at you and to hurt you. They will have no regard for the children's well-being, just see them as little pawns with which they can hurt and punish their mother.
Lunaaa, please think really long and hard about what you want for your future. The longer you stay, the more you will believe that you are nothing and that you deserve the treatment, the harder it will be to leave. Do you think that you deserve to be treated this way or do you believe that you are good enough to deserve a man that will treat you well?
