Typically, by the time we start asking ourselves whether we should let go of another, pretty significant issues and events have already arisen. When relationships are healthy and hard times arise good communication, personal responsibility and mutual effort can help us to grow both individually and as a couple - these kinds of partnerships are very much worth cultivating and then fighting like hell to maintain. When relationships are unhealthy they can become a source of depletion, by robbing of us of our precious time and energy without any benefit or possibility for change. It’s wonderful to be loved and cared for, but if this were really the case, it’s hard to imagine that you would be asking this question since most of us happily thrive under these conditions. We must seek positive relationships (and not necessarily romantic), since none of us can go-it-alone without great loneliness and isolation, but when relationships get stuck in unhealthy grooves it is time to separate, understand our own mistakes, find strength and wellbeing and move on.
