I'm developing romantic feelings for a friend. I don't want to. Should I distance myself?

It could perhaps be a good idea to do this, yes. If you feel as though your friend is not right for you, the timing isn't right or perhaps is just inappropriate, distancing yourself from them could be a good way to regress any feelings. This has happened to me before, and I found that explaining the situation as well as distancing myself helped considerably. When we build distance, we tend to think less and do more; this could open up a new potential love interest or a brand new friendship. Maybe you could talk to your friend and see how they feel.
