There was this girl I was talking to for about 3 months. We would see each other all the time and always talk. We got pretty close and I asked for her number and she gave it. Then she ghosted me over text because I assume she wasn’t interested. It is now a little awkward in person but she still says hi to me when she walks by which I find odd.
Is it best to be cordial? Should I just be polite and have small talk or just ignore her? I don’t like to be on bad terms with people but why say hi to me without acknowledging what happened?
