Yes and no. I mean, you don't really know until you actually meet her.
I remember back in high school i would always chat with girls online. I ended up meeting a few of them, some I got along great with and things went well, others not so much. Eventually I found i was better off just dealing with meeting girls IRL right away.
Partly because pictures can be deceiving i don't like being dragged through a haunted house by a girl i only find mildly attractive and incredibly annoying *shudders* that one kind of did me in, on the whole online thing.
I find relationships that are based mainly on the two people chatting online tend to be strange and awkward in some ways. I remember there was this really pretty girl i used to chat with a lot online who i went to school with. We talked at school too, so it wasn't a purely online thing, but we chatted online like every single day. Eventually it got to the point where i think she was pretty emotionally attached to me.
One semester we didn't have any classes together and i only saw her for about 5 minutes a day after our 5th hour classes she would meet me in the hallway. She would make me put her arm around her and she would say weird shit to me like "This is my favorite part of the day" she even once said she was saving her virginity for me.
I wasn't dating this girl....honestly i did like her, but i always felt weird about the relationship because so much of my communication with her was through the internet, so i never really told her how i actually felt, and eventually we kind of went our separate ways. She was a beautiful girl though, i honestly wish i had did things differently back then and actually properly asked her to go out on a date with me or something. She does modeling now...she was just in a big publication actually...*sigh*
This turned into a pitiful post of me sulking about an old high school sweetheart haha. Anyway my point here is it's important for you to meet with this girl in real life and have physical conversations with her.
Talking to someone online is completely different from talking to someone in person. Meet her and find out how you two get along actually in a room with one another before you get emotionally attached to one another and end up feeling weird and uncomfortable when you actually meet.
