I don't know, sounds like a bit of a paradox to be honest. If you mean distance, that still might work, but if you mean cut them out of any kind of interaction with you, then there really is no point. You have to choose, either love the individual and have them part of your life or leave them out of your life, and the love with it.

It might not be quite the same, but it sounds quite a bit like an attempted relationship I tried to have with a girl. I loved her, but eventually we broke all contact, so basically I was loving her without even being in her life in the slightest. It's unhealthy. If there is no interaction, I think the best thing is to stop loving the individual eventually, for your own sanity.
