Did she get bored of me?

[Jonathan Idk]

I have a friend who is a girl, that I REALLY like, but she lives in a city that's far from where I live. I used to get excited whenever she texts me. But now I just get depressed, because she either takes 1-7 hours to text back, or she just totally ignores my messages, and doesn't text back until I send her a new message. When we first started texting, she used to reply 5-20 minutes after I sent a message, than it changed to 30-1 hour, and now it's 1-7 hours or no reply at all. Did she get bored of me? I was thinking of deleting her number, because I can't stop thinking about her, and it's making me depressed that she keeps ignoring my messages, and that she keeps taking to long to reply back. I highly doubt she's too busy to reply back..

What got to head, was that maybe I was just the person she talks to when she's bored? Like I'm not really her friend, I'm just a person she talks to? Do you know what I mean? She's also involved in social media, while I'm not (It's too late for me to get involved in social media), so I'm sure she would rather talk to her "friends", than to talk to me.

What confused me though, was that she told me I was interesting/funny to talk to, and she also made a hint that she likes me. But now she's totally ignoring me? She's also not in a relationship with anybody. I don't know what happened :/
I talked to her through out my Junior year, she was a Senior at the time. And text her for about 7 months now. She's in college while I'm currently a Senior.
