Okay, the previous relationship is the second most exhausting relationship you’ll ever be in. This is the one that will leave you feeling emotionally, mentally and physically immobile. The toxic relationship is one in which you and your partner have an extreme attraction to one another, but have such drastically different morals, opinions, or integrity that all you do is fight. You bring out the worst in each other. But you can’t stay away from each other. You’re always on edge in this relationship. It’s like being on a drug: the highs are very high, but the lows leave you incapacitated.
