I can txt my T when I need to. I don't do it that often - when I have been in a very bad state I might have sent two texts in the same week but normally I try to go at least a month between txts, usually more (not counting scheduling issues, which are uncommon, but if they arise I don't hesitate to txt him about them.) I don't txt when he is on holiday.

T usually doesn't respond, and only once or twice he's responded with more than "let's discuss that at our next meeting). He never txts me unless I have txted first.
