Do I actually like my friend l? (M21 & F20)

Ok. So I (21M) was introduced to my friend (20F) via a mutual friend. Both of these friends are exclusive online friends, I have never met them irl nor do I know what they look like. When we first met, it was through a game that required 3 players. So she joins us and we are cordial, no crazy jokes or comments, but just normal talking between people that share a mutual friend. This stayed pretty normal for several months, with us barely ever playing together.

However, our mutual friend got a new job and has since stopped being online as much. So naturally she and I continued like normal, occasionally hanging out and playing the same game. Until more recently, (like the last two months or less) where we have been hanging out together online almost every day, for several hours at a time. Where we have also started to just chat and not necessarily play games, but sometimes she'll doing school and I'll hangout and be a fun distraction.

A with all of that being the case, I feel like I'm starting to grow on her as she calls me just as often as I call her. But I also feel like I am catching feelings as well. However what concerns me is that this one-sided and that its all in my head and that she might not be r8ght for me.

We've known each other for roughly 1.5 years give or take.

Do you think she also likes me or is it all innmy head and im reading too far into it?
