I'll just try to keep this as brief as possible.

1. GIrl liked me from about March-July but then got over me but now likes me again

2. I like her, but the reason we didn't go out back then was because I was dating someone else

3. She also likes my best friend (for about a month)

4. She knows I like her, and she likes me back.

5. I found out that she might not want to date me because of this liking two people thing.

Should I wait for this to pass by or should I move on?

Also, my friend doesn't like her back
