3. Don’t make loneliness the reason not to leave
Loneliness should not even be in the list for not leaving the unwanted mate. You should not forget that you have your family and friends with you for accompanying and surely there are many other fishes in the sea where there are better ones too. So, there is nothing to worry about being alone as you have no fewer people to hold on to but to leave the one which you really don’t feel like being with.
