<human>: Give me the gist of the text in a nutshell

Hi, so. 

We met at the start of the school year through mutual friends, and really hit it off a month after that. Spending time outside of school with each other became a regular thing. Whether it be dinner at her house, studying etc there really hasn't been a negative face-to-face interaction. 

They have a lot in common with me and spending time with them is really enjoyable. So a month ago, I figure I should ask her out. Why not? I haven't. Since then, they seem to be flirty (screwing with my hair, footsie etc) so it should be no problem to ask them out.

Wrong, whenever I text them the conversations always are horrible. I find that texting/fb messaging in general is very impersonal and you don't get the "full picture" of the conversation. When I text them, I often get confused replies if at all; that completely destroys the self-esteem I've gained from all of the face-to-face interactions we've had.

Right now I'm a bit lost on where to proceed with this all, they seem to be giving obvious hints but maybe that's just their personality and I'm reading it all wrong. Thoughts?
<bot>: Hanging out often with good friend, they seem to be giving obvious signs of interest. However their replies to texts seem to be confused if they even reply at all. What's my next move?
