Why would he admit fault or regret, though? I get that you are hurt, but I honestly don’t think your T did anything wrong. He’s not a mind reader.

I think it’s totally fair to go in there and express yourself- say hey, I never ask for extra help and I was hurting the other day, and felt like I needed some support and texted you, and didn’t feel satisfied with your response because _____. Take the conversation from there, and perhaps in the future should it come up again hopefully he will know how to help support you better. But I don’t understand how you can be disappointed when he inevitably doesn’t express fault or regret because he didn’t read between the lines.

That’s just me, though!
