This might sound rather odd, but I think actual love necessarily risks pain. It's easy to see why; if you love someone or something, you'll suffer when it's gone, right? But a lot of importance is placed on the idea of "being happy by yourself" and being able to get over people easily and such nowadays. I'm not saying you shouldn't strive for independence, I'm saying true safety and healthiness comes at the cost of strong love, since love comes with the risk of being without the thing or person that you love. Whether you choose healthiness or love is up to you. Now as to how this applies to your brother; his opinion on this is great for his happiness. Being able to move on means that he won't be burdened by the thought of your death. However, that of course means he is okay with, for the most part, 'forgetting' about you in day-to-day life, as that is what it means to move on. I'm not coming to any conclusions on whether that's right or wrong or 'selfish' or what-have-you, because that's just up to how you view things. He said it was to honour your memory; this implies that he thinks your wish for his happiness is above your wish to be remembered by him, which could also imply this is how he thinks about you, but it could also be a weak justification; I don't know anything about your relationship with your brother, though, so I'm just offering possibilities. Hopefully my thoughts on this topic were helpful.
