<human>: Can you condense the text into a few key points?

My first post ever.  So a little background.  

I have been seeing this girl long distance for almost two months now. We have known each other for years and at the beginning of April we got together for a 4 day theme park trip.  Lot of fun and things turned romantic and intimate. We text fairly often and we have spent 2 long weekends together the past few weeks at her place.  

After I left her place last weekend we texted briefly on Monday and Tuesday, both initiated by her. So last night I texted to say hello, she responded a few minutes later, and then I said "I was thinking about you today so I just wanted to see how you were doing." 

I never got a response back so now I do not know what that means.  The last weekend was pretty good, but there was a little weirdness the last night. She was really drunk (I no longer drink) so I just chalked it up to that.  The morning I left she was affectionate with me so I didn't think much of it. 

If she had wanted space I wouldn't think that she would have contacted me the first days after the weekend. So I am kind of lost here. Not sure if I am just reading in to it too much or what. Any ideas reddit?  Have we known each other long enough that I can send a follow up text (don't know what yet). I know that is against normal dating rules but since we were friends first I'm thinking that might be different. I can provided more info if needed. Thanks.
<bot>: Dating a girl long distance for couple months, never heard back from a text telling her I was thinking of her and wanted to know how she is doing. Wondering if I am over thinking it.
