there's more to love than romantic love. even when someone talks about a 'true love' it isn't always romantic. you can love anyone or anything, to not feel love would be a terrible thing, you wouldn't love your pets, your friends, your family. on one hand you won't get hurt, but on the other you wouldn't feel the joys of loving another. one of my favourite quotes [talking about the old 'tis better to of loved and lost than to of ever loved at all']
Well, he's acknowledging that if something makes you feel good, like being in love, there must be a corresponding painful side, like losing at love. It's just a fact of life. And what's intriguing about it is that no-one calls Tennyson a big unhappiness freak just because he understands that. He's a realist. He says that emotional involvement can bring pleasure *and* extraordinary pain. Then he declares that it's still better than never feeling anything at all.
if you wish to not feel romantic love, that's fine, it might show up at some point in your life, but it's not something you'll search for. [personally, that's the best way to find love] if you don't want to feel any type of emotional attachment, you'll life will be a hollow existence indeed. you'll shield yourself from pain, but you're preventing yourself from living. it's your life, and your choice, but don't jump into this without thinking if you're serious.
