It's very very hard to do it. I love my fiance with all of my heart, but I've learned to keep this secret so well I hid it from him unintentionally. Now he has found out, and he doesn't know what to think (more of because he was hurt that I didn't tel him earlier sort of thing, the fact that I hid something from him.) Now I have to find a way to sit him down and talk to him about everything (To those that thought I was going to talk to him yesterday/day before/whenever I said? I was, but then he had to take a trip to colorado to get the bastard from my rant away from me. So I STILL haven't sat him down yet

.. )
I know he loves me no matter what I am, but I don't know how comfortable he is going to be with everything. He had offered me blood from wounds in the past, but never really thought why I wanted it. He just up and offered it to me because I was staring at it.
I don't know if he is willing to be my donor, and I know that he wouldn't accept me having a donor other than him, which means I either have to A: Try to lean myself even more to psi than sang and try not to ever think about blood or B: have a donor behind his back, which I am not willing to do unless I get much crazier with these withdrawals than I already am.
Believe me, it's a hard hard process. Whether your woman is psi along with you or not, you can't help but feel the way you do! We teach ourselves to be so hidden we almost fool ourselves I think at times.
Just try to relax, find a good time when you and her are sort of 'ebbing' together in my opinion (You guys are cycling energy and connecting amazingly) and just bring it up. Talk to her, tell her your reasons why you haven't been able to say anything, just confide in her. If it all starts to be awkward, then opt to talk about it another time, ask her to come to you when she feels ready to continue the conversation.
