Michelle, it depends on what you believe. Some people think they go to another world, a heaven or hell. Some people think they are sitting in the ethers above us, watching and intervening if necessary. I personally think that we are all part of the same consciousness. If that's the case, then yes, they are with you because they are you. Furthermore, you will always have them in your mind, which is you. So, technically, they will always be with you.
