I know how you feel! I feel the same way!
Two hours a week I feel like the T is mine, and no one else can have her - like a child protecting their best friend so no one else takes them away.
I haven't really admitted this to T, but she knows Im attached. I love her a lot... and often wonder if I should ask her if she loves me (us) in return and if I'm allowed to take that love -- if it's unconditional. But, fear stops me, every time.
