Does this girl like me romantically?

I am posting objectively here without any slant as I want the truth, not the version that I want to hear. Met this girl while volunteering at a local charity. She was initially friendly to me, shared about her day jobs with me, the ups and down, etc. We got along well as we shared our stories. This happened for the first 3 times we were volunteering together.

Subsequently, during the 4th time we met, she became very quiet and didn't talk to me at all. She focused on her tasks and didn't even make conversation. The first 3 times, she would ask if I want to get a beverage (as she was buying as well). Now she would just get her own beverage without asking me. Fair enough, everybody has a bad day.

To clarify, I didn't chase her or make advances as I err on the side of caution (She could just be friendly, I think). 5th time we met, as usual, she didn't talk to me at all at the charity and did her own thing. I did my own. As we were walking back to the train station, I asked her whether she read the latest news and we started talking again like the first few times. We saw each other off but after that I realized she removed me from her Whatsapp contacts (I could see her DP and status earlier).

Subsequently, during the next week, when I texted her whether she is going to the charity the next day (I text weekly just so that I know the time I need to reach there, if she isn't there, I will go in the afternoon since I am on my own), she will reply quickly (or within a minute) and then add emojis (which hadn't happened earlier at all), saying she could go or not. This happened for the next few weeks, she will reply immediately to my texts with emojis. But when we see each other in person, she will be quiet, won't talk to me and sometimes she will talk to other girls instead. But when I told her I am washing the place, she doesn't say anything but she will proceed to use the floor water scraper to dry the floor.

I am confused on the signs.
