I think I like this girl but I also feel like I don't know her?

I (20) met an online friend (19) through a game about two years ago. We talk almost daily and lately I've realized I started feeling... things. I don't even know what she looks like and I still feel all gay when we talk. I like being in her company and listen to her talk and laugh and hnnnnng.

We have plans of meeting up (we live in the same state and remotely close), though we don't have a set date yet.

This has never happened to me before and I hate/like it at the same time. I guess it's the fact that it's online that throws me off? But I know relationships can start online and ugh feelings are weird.

I have no one else to talk to about so I quickly made a throwaway to vent about this gay ass struggle haha
