I approached this girl at the gym who I’ve seen quite often, wanting to get to know her. It worked out well cuz we were waiting for the same machine and we ended up working in with each other. There was good banter and it made sense for me to suggest that we hangout sometime. So I did and got her number. We started texting and then she just stopped answering; it’s been a couple days already. Do I bother to double text her (if so, what would I say), or do I just wait to start a new conversation when I see her at the gym?
