I'm sorry if you already posted this elsewhere, but why won't you see your T for 2 months, and why maybe not ever? That's so sad. I understand how you feel about never knowing her, but haven't you gotten to know her somewhat by being with her for some time? I forgot how long you've been seeing her. You may not know details about her, but I don't think anyone we see so often is truly a blank slate. Don't you know her "essence", for lack of a better word? I bet you know her better than you think you do.

Maybe you left already, but if there's a chance to say "I love you" and you'll regret not saying it, I think you should say it.

I hope your session goes all right.
