Thanks everyone...all your suggestions r helpful...and are giving me confidence to talk about it.
when i was in deep depression, i was cutting daily...never told T about it..and he never asked or suspected. I never brought it up as i saw it as harmless and had no intention of stopping.

now i have stopped SH completely...i get tempted but i have been successful so far.

I am feeling more confident in telling him that before we delve into these scenarios...there is a down side for me...i may start hurting myself afterwards . there is no win for me here. i can stand tall and face it...then come home, and hurt myself.
