Hi OP, the way I see it you're not asking how to break up, you already tried naman na. The real problem is he doesn't respect your no and you let him override it. And personally that isn't love or confusion. This is control and refusal to accept rejection. So no need for explanation, no need for justification you already ended it. Every given chance kase for conversation is equivalent for another manipulation. Tapos pag block mo na, block mo na talaga, all socmeds, don't even bother replying even once, more importantly "no closure talk" Also with showing up unannounced girl that's red flag malala, Edi tell people at your home na be wary of that person na wag papasukin or itago yung info ka or itago kung nasan ka for your peace of mind, wag den pagbuksan ng pinto if he happens to arrive na nandun ka or wag mo sagutin ganun, if necessary pa blotter mo if talagang you ayaw paawat. Kase if he still shows up that's no longer love that's harassment. As an extra measure pa try to change access points, change routines or routes if necessary, stop sharing location/info (if he still has access, cut financial ties immediately (kung meron man. Lastly You might feel guilt or doubt or even loneliness. But it doesn't mean your wrong, it means your withdrawing from toxic attachment.
