What to do when you don't like some one for who they are but you love them?

I hate so much about him and his personality. I hate so much about how he lives his life and how he makes choices. But I love him so much as well. My emotions are so conflicting that I am at a loss here. When we hold hands, when we hug each other, when we look into each others eyes, when we laugh together, when we actually connect…. I feel so much love and care. But His lifestyle choices are so conflicting that I just don’t know what to do.

I can’t just find some one else, and it’s weird, but I almost don’t want to. I love who I love, and if I left him an empty spot will sit in my heart forever. I don’t know how I can live like that, or anyone. I feel like I am trying to hold on to something that will never change, but I feel like I HAVE to hold on. I just can’t come to the conclusion of letting go and being okay for the rest of my life…. I just feel like some how… some how we can change and make things better. How can it impossible?

I’m asking for some personal opinions from people with experience. Is it worth saving or would I be happier in the long run if I just let go…?

It feels weird asking strangers this, but I really have hit a brick wall. Not even my friends can help me. :/
