How can you tell the defferance between a crush and stalker potental?

I am now waking up at 7:45 so I can text him. He wakes up early so he usually texts me around eight. I hate to wake up and find that there was a txt from like 4 hours ago and he's away from his phone. I get sad when I txt him back a few hours too late and he can't text me back because he is too busy. great....I always wanted to be a stalker (sarcastic)
