i feel… defective

i was talking to a guy and i liked him. i really liked him. we had a good day. spoke about the future, wanting to go out etc.

he went to do something and after awhile i went back to our telegram chat and he had not only deleted it, but his whole account. he even deleted his reddit account. just poof. fell of the face of the earth after saying he wanted to marry me.

i have had to deal with worst interactions, but i thought its fine as long as i found one good guy, one guy who was worth it. i thought i did.

why does it happen to me? why does it have to be me that deal with this nonsense and gets her heart broken? what’s so wrong with me?
