<human>: Talking with this girl whom I first met on tinder. Eventually got her number. We snap chatted and texted a lot. She showed me her body and I showed mine. We were gonna meet up, but it was always interrupted by my work. She said things to me, like "you're my favorite <3, come over, I just wanna see you, I wanna fuck you more than once, I don't know if we'll make it downstairs (before going at it), etc." Had her as a friend on facebook and everything. This was going on for like the past week. 

TODAY, she said "I'm her favorite" and then later I find that she removed me from snapchat, facebook, and isn't responding to my (only) text. It says on facebook that "Rj has my heart." Must be a new relationship..

I just don't get it. Why say all those things and then, BOOM; nothing? I get invested really easily and would like to know how to not get hung up on one girl so much.

Provide a brief overview of the text.
<bot>: Girl was getting invested in me (or so I thought) and then deleted all contact with me. Why would she? How do I not get so hung up on one girl?
