So texts have become like a ringing telephone - one doesnt have to answer.

I think the issue is that, texts are for communication between people who are in each other's personal space, albeit temporarily distanced. Psychologically they share space and the technology makes it practicable. Just because you use the technology, doesnt mean you have really been welcomed into that space.

So maybe you need to figure out why closeness is lacking in these relationships? Is that what you are asking?
