I think the best person to talk to about all this is your therapist. Having said that...

I have to wonder what would be gained by telling her. You don't sound like the whole thing is terribly distressing to you. It doesn't sound like you NEED to get this off your chest. It doesn't come across like you even need to change your behavior to be true to the way you are. At least that is the impression that I got from reading your post. I am not one who believes that you have to tell your partner every little detail of what is going on inside you. If I did my partner would go nuts and finally leave me because he couldn't tolerate hearing that at least 6 times a week the thought of killing myself crosses my mind. No, I don't want to kill myself but he would not be able to understand that thinking about is not the same as wanting to do it. So I truely believe that there are things that should not be shared with ones partner for their own sake. So ask yourself, what would she gain by knowing this about you? Would you be telling her for her sake or for your sake? Would this be something that could improve your relationship? Is it something that is detracting from your relationship now? I sometimes think that people confess to something "because they deserve to know" but really they confess to make themselves feel better because the guilt of the secret is so great. That is not a bad thing, I just think that one should be honest with ones self about the reason for the confession.
