Thank you so much for the responses. It really helps to get some perspectives.

I should have said that T almost certainly received it as I use delivery reports and I got one as usual soon after sending it. It's possible she couldn't open the file but then I'd have hoped she would have told me? If that is the issue hopefully she will tell me in my next session which would clear it up.

If she doesn't, I guess like you say Rive she probably didn't feel it warranted a reply. It's just me being literal about it - she said she would always reply and she has not!

It's interesting what issues this has brought up for me. I know in my heart she's a safe T, but this has made me feel decidedly unsafe, as if she could suddenly pull away from me and not care. I'm experiencing her as uncaring and even seeing her latest text (text2) as less warm as her previous ones, due to the fact she didn't reply to text1.

It's crazymaking it really is.

I don't know whether to let it go or mention how I feel about the lack of response. I guess I could play by ear depending on if and how the subject of the file/text comes up.
