Most Helpful Girl
It's not a bad thing.
When I met my ex in high school (junior year), he and I used to IM constantly for several hours a day. We started dating 6 months after we started talking, and we were in a relationship for nearly 3 years.
My ex never really talked on the phone with me, so we exchanged thousands of IMs per day, and hundreds of long emails over the course of a year.
To give better perspective, I've been seeing a guy for about a month now and we've known each other for 3 months. We constantly email each other. He even prefers to text me rather than call when we're meeting up somewhere, but when we do meet up he's pretty chatty.
It's not a bad sign that he doesn't call you. It really depends on the guy. Most guys don't like phone conversations at all, unless they're very, very outgoing and talkative.
Maybe the guy you're talking with just isn't comfortable with talking on the phone, or maybe he's not ready yet.
Try calling him for random things, and casually extending the conversation.. see where that leads. Maybe he'll take the hint. :)0THIS IS NOT RELEVANT ANYMORE
