if its just the fact that you have bp I wouldnt let thu stop you. She already knows what she has in you and I hear you when you say that you dont want to hurt her. I sometimes feel extremely guilty about what my husband has to put up with with me and my bp. Maybe you could try therapy together to find ways that you can deal with it within the relationship? You cant leave yourself all alone because of fear of what you might do. People get hurt when no bp is involved to. Its just the risk we take in love.
