Indeed, that is a tricky one. I will say that in the past, I have always given my therapist space regarding these issues.

I have never regretted it at all.

That is not to say that you should tell your therapist that all is perfect, but I would respect where he is right now and let him be.

When he returns all is fair once again.

I'm sorry your upset, and I'm sorry this is coming at a time when your therapist is not there to support you. Do you have other modes of support to help?
