Talk first. But if communication doesn't work, leave when you're capable enough already. If in any case, they learn whatever they did wrong instead of shielding their mistakes with stupid shit like "your my child", and stuff like that and you forgive them, it doesn't mean that reconnection is a must especially when you don't feel safe around them and shit like that or sumn

It is. But you also have to recognize when communication isn't a solution. Abusers and manipulators use communication as an opportunity to subdue their targets. Against emotional blackmail, trying to establish dialog is the opening they are waiting to guilt trip you and manipulate you into doing what they want.
Against narcissists and other malignant personalities, cutting contact is often the best option. Communication don't work if the other don't want to communicate, and trust me, when someone use emotional blackmail they aren't trying to establish an healthy discussion. By trying to talk it out, you positively reinforce their actions by giving them the attention and compassion they wanted to obtain when they blackmailed you. Rewarding them for manipulating you, augmenting the chances of them using the same tactic again in the future.
Those who use death to emotionally blackmail others actually deserve to die with no one's compassion.
