I'm sure this is true; but I haven't seen any evidence of it in this T's interaction.

CE:That's not at all how it feels to me. If my T is unsupportive, how can I trust her? And if I can't trust her, how can I advance?

I don't think it does feel like this for you. But your feeling that your T is unsupportive doesn't necessarily make it so. Where is the evidence? You seem to equate disagreeing with her perspective with a lack of support. And if you're willing to abandon all trust because of one perceived transgression, your notion of trust is distorted.

I just don't see your willingness to be part of this relationship. Instead, you hold your T to some standard of fantasy perfection, get angry when she doesn't act accordingly, then feel aggrieved, issue an ultimatum, have a rupture.

I don't know what happens during the ruptures, though since you're still seeing the T, there must be some sort of resolution.

Is this like an attraction to make-up sex? Do you crave the post rupture honeymoon? There has to be some felt benefit to continue this.
