Thanks for the insight and responses so far. Puppy, I haven't investigated, but I am going on faith that we still have enough of a respect for one another that she's telling the truth. I believe her at this point. Naive or not.

Saffie, I will try finding out what she wants and needs in therapy tomorrow. Only second session, and I am being cautious to not push her farther away. Our relationship has always (to my knowledge) been great...loving, fun, etc. It has not been as fun in the past 8 months, and not as loving for the past 4 or 5. I hate this and the fact that I don't know how to fix it. I don't have any tagibles to work with, just "i don't love you."
