Most Helpful Girl
Just text her. Maybe she waits for it?
I don't think she could be that busy to not text you for a week.
I usually don't start convo as first. And I can wait week for him to text me. I don't like being clingy.
There's a thing I also don't like but I don't know about other girls.
Don't start convo with "Hi, what's up?" better start with something like " Hi, did you saw this movie" (this is only an example. But it's better to start convo with dropping funny photo, maybe a link to youtube, something you're both interested in.)
