I get that feeling. I have been tempted to go in and lie frequently but, as someone pointed out, the only person I am hurting when I do that is myself. I do struggle with holding some feelings back from her though so I guess that is a lie of omission if you want to get technical. Usually I dont realize what I am doing even though but when I do, I find a way to bring that up too. *sigh* In general, I try to be open and honest though. I'm not paying to make her feel better about herself and I'm paying to talk about hard stuff and have her help me work it out and she can't do her job if I can't say what I need to.

I would recommend telling her the truth but also tell her how difficult it was to admit. It could be illuminating for both of you.
