Ex-gf wants to visit me sa Manila to beg for me to come back

Problem/Goal: How can I stop my ex from coming to Manila just to beg me to come back sa relationship.

Context: So I(M) broke up with my gf because I feel like I’ve fallen out of love and I think it would be hard for the relationship to continue if ganito ang nararamdaman ko.

I broke up to her sa video call dahil LDR situation kami. Taga probinsya kami but I’m studying here sa Manila.

Now, after our breakup, I didn’t blocked her fully since it pains me to do that to her kaya natatawagan pa niya ako via phone call to beg for me to come back. Ilan beses ko na inaffirm sa kanya na firm na ako sa decision ko and I don’t think I can come back na sa relationship.

Don’t get me wrong she’s really a good girlfriend, I guess the problem was me.

Since ilan beses na niya ako tinatawagan, I then decided to block her phone number na para malaman niya na firm talaga decision ko.

Ngayon, she emailed me na she’s going to come here sa Manila to try to talk me out. I replied na huwag siya pumunta since dangerous dito if hindi niya kabisado ang lugar. Ilan beses ko na siya nireplyan sa email, pero mukhang tuloy talaga ang pagpunta niya dito.

I’m just worried paano siya pupunta dito at paano rin siya uuwi considering it would be awkward na same pa rin ang maririnig niyang sagot sa akin.

What should I do guys?
