I agree that just stopping can eliminate turmoil. Do you feel you don't need to text him, do you feel you are doing it to protect yourself, do you feel your relationship with him is stronger or weaker without it... ultimately, is it any healthier for you to create the boundary/rule for yourself to just not do it, not risk it than it is to learn how to tolerate that a lack of an immediate or prompt response from someone that we know cares about us, and that the delay or even a lack of a response doesn't mean that they don't care about us?

There is no right or wrong answer here (and no need to respond to me either)... I battle with this one completely, as it is very easy for me to go to the... fine I just won't do x again.
