struggling ...

I can't get over my ex, he has ended things, he won't talk to me because he says it's leading me on and won't meet me. 
No matter what anyone says, I just can't get over it and I am just so unhappy at the moment, I feel so low and I haven't stopped crying. 
I can't bring myself to delete him off social media, but he is posting things and acting like he's as happy as ever ... I just keep hoping that giving him space will make him change his mjnd 🙁
I feel so alone.
