I've done it many a time. The last story I told started online initially, and we eventually moved to talking on the phone and then living together. Didn't work out for other reasons, but I've been around the block too many times to be fooled.

Currently, I'm dealing with someone that used to be fun to talk to, but she's being super clingy and annoying... and we haven't even met yet. I can't deal with this nonsense.
