At some point you have to acknowledge that you have to cut ties with some people for your own mental sanity's sake. Could be people you've known for years, or people you love, and so on. Because if that respect is not reciprocated then eventually you're going to get stressed out and that's really destructive for your body health.
It can be as simple as not talking to them anymore or seeing them. But the truth is that many of us eventually have to confront this feeling at some point in our lives.
