People tend to ask for support when they are upset, and so what I think you see on this board most is the kind of events (mostly with T's, but sometimes involving other people) that push people's buttons.

I've had numerous T's and none of them have followed the pattern that you are worried about. They have all been helpful and supportive to me at various points in my life. I've felt safe and secure in all of them, including times when I had fleeting attractions or fantasies, but those ended up not really going anywhere. So it's possible to have transference like feelings for your T's without them going anywhere or even becoming an important force in the T. As others have said on this thread, there are a wide range of experiences here and only some of them fit the model that you are concerned about.

After all, it really wouldn't make much sense for me to post "I am NOT having strong feelings for my T in the romantic or unboundaried way that others have them"!! First of all, such a post wouldn't be useful for me, it would make me seem like a tool, and it wouldn't do much for the community unless it would help for others to unite in what a tool I am.
