Ex gf

1year ago , I still remember how my ex act normal when we already brokeup , I ask to meet her and eventually we met , she was acting so sweet and normal to me , giving me hugs as well , but the moment I reach home , she became a different person , cold , distance , leaving me on read , no replies , busy , I was so stressed and depressed back now that when I think about it , I still question how come she pretends to be normal and caring while becomes the complete opposite when im not with her , I wonder if her love was even real sometimes because I would have never pretend to be cool and sweet infront of my ex and hugging her and stuff, while in text to be completely detached, cold , distance.

I really thought we would be getting back again but her behavior changes the moment I left , I remember I was celebrating her birthday with her even though we broke up....I really we would get back together but nope...she uses me just for that day and it was the last day I ever get to meet her....from that day onwards, she ignored , she reply late , she would full day without even reading my text , she would be sooo distance, it still hurt me to think of it....my thought is , why is she like this ? Does she even love me anymore? I'm soo confused seriously
