Recently I've noticed some things. She's been texting me more than usual, always inviting me to lunch either by herself or with her friends (and picks up the tab for us even though I decline) and being more comfortable around me. Sure she still talks about other chicks in front of me, but it's more of a hesitant type of way than her usual outspoken one. She also gets really defensive whenever someone assumes we are a couple because of how much we hang out together. She even told me our mutual friend brought this up and said, "well if you want people not to think you're together you shouldn't act like a couple," and didn't really know where she was going with the conversation so she slowly changed the subject. I tried asking her casually like "what?" but she shook it off and began talking about something else.
So I'm confused a bit. And I really don't know what my feelings towards her are right now. Like yeah I liked her but she told me basically I didn't have a chance and now I feel like it's the other way around. Your thoughts? Is this normal in a budding friendship or could this potentially be more?
