Is this the end of my marriage?

[P17]

I got a reply to my text of yesterday (about dating others) and my voicemail of this morning.

She thanked me for the text and voicemail. She'd like to see the email sent to me by my D's Social Worker to see what she suggests (although the Social Worker suggested nothing) and my W will bring her diary on Monday so that we can talk it through with me and my D.

That was it. Short and to the point. Don't know what to read into that if anything. It doesn't really warrant a response.

I actually get the impression by the 'tone' of her text (she usually signs texts with her initial), the feeling that she's kind of ignoring me and the contents of her texts that she has taken the hump / huff (not sure what you guys call it in the US). Her texts are usually kind of up-beat but the last few weren't. Again, maybe I'm reading too much into it but I'm not so sure.
