My T has encouraged out of session contact more recently....he basically said that he would let me know if I crossed some sort of boundary but he doesn't think it'll be a concern with me....I say how does he know?

I mean, I'm not sure how needy the parts of me are underneath. They're locked up tight and will be ravishing if I let them out.........I'd rather a clear "Freewilled you can email me x number of times per month." But that doesn't seem to be the way it works. It's all so flipping confusing to me! I hate the idea of bumping into a boundary and not meaning to....
Can you ask your T about it? I wish I could've been more direct about it, but I did tell him my concerns about taking up his time outside of sessions. That opened up the conversation for him to reassure me that he would let me know if it became a concern. Ugh. So complex - this relational stuff.
