Insight is intellectual. I love insight, find it absorbing; but insight doesn't heal emotions. So I guess the question to answer is, where does the pattern that you want to change reside? If it resides in cognition, then non-attachment type therapy, like EMDR, CBT, DBT, RET, etc can be helpful.

But if the pattern resides at an emotional level, then I think it takes emotionally based therapies to heal. And those therapies involve attachment to some degree. And if the pattern is attachment-based, I don't know about any effective approach that doesn't activate the attachment.
