text: What's happening seems natural. \nSince you told your friend that you would take care of her, you have to really carefully analyze whether what you feel could last forever, or whether it's just passion, as if it were just a momentary desire for her, you would break the promise made to your friend. \nI think that, if you really love her, and want to spend your time with her, there is nothing wrong, and nothing that interferes with the promise made to your friend. \nThe next step is the difficult one, which is bringing the subject up to her and having her feel the same for you. \nIf you have been getting together very often she probably will end up sharing your feelings, and wanting to be with you in a more complete way. You have to be very sensitive, though: if you friend died only this march, she's probably not at all ready to take on another relationship. Even if she thought she were, it could be an illusion, or just a desire to be fine again. \nPeople need some time to fully recover from shocks as the death of someone loved, and don't get back to their normal selves (although they sometimes are not really aware of this) until some time has gone by. \nGive things time, and take them with a lot of patience: always show her your love, but don't ask her to love you back until she's ready, and don't bring the issue up until she shows you some hints pointing at her love for you.\nGood luck, and best wishes.
