This is based on online interaction:
I recently got a phone number from a girl I messaged back and forth with after about 3 messages. The conversation pace seemed to be going good, and I said something like, "you seem really nice and I'd like to call you sometime, messaging on here does't feel the same as talking in person." She replied with "yes, i agree " She gave me her name and number and I waited to call the next day. No answer, and a voicemail that was not set up to work. Tried an hour later, same thing. A couple hours later, I sent her a text saying it was me, asking how her day was, and to call when she got a chance. Still no reply. I saw she was online later that day, but I didn't try to message her back online, thinking that would seem too stalker-ish for one's days attempts.
Im fairly new to the online dating scene and have been trying it for a few months now. I'm getting some replies now from about 10% of the girls I send messages to. About a month ago, I was still getting the same number of replies, but then the communication would stop between about 2 to 5 of my messages back to them, (possibly from not asking for a number or suggesting a date). So, I suppose I've possibly been improving my conversation pace with trial and error, but still got a lot to learn.
Bottom line, any pointers, advice, and constructive criticism would be welcome. Specifically on conversation pace/number of messages back and forth before asking for a phone number or a date, how to make the transition from emails to phone to date, and keep from getting blown off.
