So theres a girl I work with, she cleans rooms and I do grounds (outside work) but I don't work there every day. I saw the signs, every time we see each other she gives me a huge grin like she's happy to see me and we talk but not for long cause we workIng. I asked her to the movies Sunday and she said yes and we exchange numbers. Now here's the weird part, we text but the response from her just stop. Like, I was telling her something funny that happened at work and she responds by laughing and agree how that moment sucked. But I asked how everything was going from her end she just stopped texting even after her work hours were over. Naturally I didn't want to blow up her phone so I texted her a good morning today and she responded we talked about how hot it's going to be before and told her I wasn't going to be at work and again no text back. I'm not trying to be paranoid and I'll see her tomorrow but should I be concerned?
