Many emails before meeting online dating
For me, I generally try and shoot for a number the first night I'm talking to someone as we sustain a conversation. To be clear two weeks only happens of there is strong intention to meet when available.
If it clicks (no matter if for friendship or potential dating) after a few messages or during chat switching e.g. To be honest, I'd meet with someone from the Internet without talking to that person at least once or twice on Skype.
One girl I was messaging wanted to text a bit, said she was new to online dating.
