<human>: Give me a shortened version of the text

We have been dating (long distance) for two months and I had gotten the feeling that things were on the way to becoming serious.  Also we were friends for years before we started dating.  

So last time I went down to her place we talked about going to a concert in July that her friend had tickets to.  Said I needed to make sure I can get off of work. So Sunday, a week after I last saw her, we had a normal conversation. On Monday I found out I could get the time off.  So I sent her a text saying I got the time off, should I buy the tickets? 

I have heard nothing since then other than a like on a random Facebook status.  I find that a little weird.  There is no rush to buy the tickets since I am buying them from her friend.  But in my head I have gone all over the place as to what it means.  Everything from she doesn't want to see me any more, to maybe she is getting cold feet about where the relationship may be heading.

So I'm not sure what to do.  I do feel it is rude to not have gotten a response, but I know that I just may need to have some patience.  My current thoughts are to just wait, and if I haven't heard from her by Monday then attempt to contact her. Does any one have any thoughts on this.  I have also been known to over think things.
<bot>: Girl I am dating did not respond to question about future plans we were making and I am not sure how to take it or what to do.
