Most Helpful Girl
There's nothing wrong with how you are feeling. I've had that same situation happen to me before. You see someone's profile and you become interested in getting to know them. So you both exchange a few messages and it's going really well. All of a sudden you start to feel excited when their name pops up in your inbox. You read and become more and more attached to them. Even though you haven't met them in real life yet.
There is such a thing as online chemistry. But you have to be careful because chemistry may be online but not in person. I've had that happen too.
I know people think it's silly, I've been told that too. But it's not. We're humans, and if you are on a dating site you are obviously looking for some sort of connection. It's exhilarating and addicting when you find someone who seems like a good match, and it can be fun learning about them.
But it's hard. They don't always see you the way you see them :(
