I think you should tell in the first few dates of your problems. With my current fiance' we both have problems and we started off as friends/roommates. We spent a lot of time talking to each other about our problems, past relationships and past abuse. It really helped us in understanding each other. Now 6 yrs later we're still together, still fighting our past demons with each others help and still very much in love.

I hope it works out for you
