<human>: Condense the text into a few key points

I've (21M) been dating a girl (19F) for about 2 weeks now. We've both taken each other on dates, and both of us had a great time each time. Good chemistry, we almost starting banging one time when people were in the other room but decided that would have been weird for them and didn't. We talk fairly regularly and easily, but I've noticed that I'm always the one initiating contact.

I'll text her, she responds quickly and we can text for hours. If I don't text her though, nothing happens, it's been 3 days now where i haven't heard from her. I asked her 2 different times if she was available for meeting but she would say she was busy. Meanwhile, she is posting pics of her hanging out with her friends not long after.

Should I keep going or should I throw in the towel. Feel like I might be over reacting but I have been lead on before and I know the signs pretty well at this point.
<bot>: I (21M) feel like this girl (19F) has lost interest and won't say it. Do I stop trying?
