This guy at work

I have hella fallen for this guys at work and I don’t think he has ANY idea and it HURTS. He has a reputation for dating a coworker at another location but they broke it off a little bit ago and I don’t know maybe it’s just too soon for him, but I’m such an introvert that I don’t know what to say to him, I can’t keep a conversation. I can only stare from afar and wait until we are alone to really have a conversation until I grow some balls. He sometimes texts me when I get off of work at 1:30am if I got home okay and it melts my heart, he’s so sweet and such a gentleman and that’s really rare these days. Someone help me 😂😂
