<human>: My gf she acting very weird these days.

We are on LDR and she said right now she can't love me and doesn't have feelings for me and I also asked about whether she's seeing someone else , she said no. She also told me she loves me and Can't let me go also. 

She's changed and I can't find the previous one in her, she's in confused state. 

Also said - "I love you but I don't have any goosebumps when i think you like i had in previous."

This is my first relationship and her is 3rd and I feel like terrible that I'm only doing the things for her and stuffs.

 It has started to drain me by pondering she loves back or not because i have given my all to her.. we had been physical also past month.

Feels like a crap.. few months ago she was fine and good had concern for me now its all gone ! What the Fk is she doing ?

Can you provide a brief overview of the text?
<bot>: what should I do. It's draining me, or should I wait for her or split-up / give damn?
