I used to call my ex-T's vm alot, just listening to it gave me some comfort, although honestly, it was never enough. My current T and I text alot, and that has been extremely helpful, even if it still feels a little odd to me.

So I say call her vm as much as you need to. And the attachment stuff is hard, and it takes a long, long time to work through. Like you, I tried fighting it, denying it, resisting it, but with my current T I'm starting to accept it, and it's making all the difference.

Good luck
