heartbroken

so i was just chillin in my room geting ready for bed, when i thought to myslef "wow its been like four days without my gf calliing me, i wonder wassup" (ofc we sc and stuff but like we normally talk otp everynight or every other night). so i call her and for the first twenty minuites it was really akward so i knew sum was up. and like i just felt it. n then she said like "this is too hard" and the next fourty minutes was spent crying, and trying to talk. but apparently i was the best girlfriend ever she just couldnt do the distance anymore which is understandable ig. it just sucks because i never let my guard down for nobody and i did for her. i dont ever give anybody a chance but i did for her. why. just why. this is my first real relationship like i dont form connections like this with nobody. i thought we were chilling, i thought maybe something was up w her but not all this. its just so hard bc i was so unprepared for this. today was our 18 weeks. she told me she loved me like two weeks ago and now this? it was just so unexpected but i cant say that i wasnt starting to feel the same way. long distance is hard. but like we met for four days, i spent so much money that i fr didnt have to rent and airbnbnb and go see her. but i was falling in love, i woulda done anything to go see her. i still feel like it could work, like it was working. i just dont understand. like i sent her stuff in the mail, i texted and called her all the time, i set up movie dates and mincraft dates,updated her noteit daily, i just did such cute stuff, like the relationship was working for me, but i guess not for her. maybe its for the best, who knows if its meant to be, its meant to be. whats even harder is we didnt break up over some toxic shit, like i cant even hate her. it was like a healthy breakup. like do i snapchat her, do i ignore her? i cant even talk to her bc wtf do i have to say that is like "Friend" based? you know like how do you go from loving a person and being like super friends on snapchat, to just not talking "bc it wasnt working". i littereally powered off my phone and threw it. i dont think i can ever open it again. like do i just pretend she doent exist? i really hope she was truthful and faithful to me, caus ei think i would legitemitley die if i found out i got cheated on. i dont understand i feel like i do everything right, like i am relationship perfect. so why does this keep happening to me?!
