I think I made a mistake

I made a new friend a couple of weeks ago and we got along really well. The thing is, last night I couldn't get to sleep and somehow we ended up sexting. She's a girl, btw.

The thing is, I got really turned on by everything she was saying and couldn't stop then, so we kept that dirty talking for about two hours.

Today she's acting really weird. And I'm scared we'll lose the friendship we made. I like her and I really want her but it's a long distance kind of thing and I don't want to end up crying.

What should I do?
