Signs You're in a Toxic Friendship

Building relationships with people is part of life. We all form strong friendships that make our lives healthier and happier. However, some friendships may be more harmful than they are helpful.
Friends celebrate each other's happy life moments. If you find you're generally uncomfortable to speak about your job promotion etc., chances are, you're involved in a friendship with someone who is competitive or jealous of your success.
They always call you when something is wrong with them but never seem to have time for you when you have a problem. They expect you to be there for them when something goes wrong but are nowhere to be found when you need help.
They always break their promises.
Honesty is important in any relationship, and friendships are no exception. However, it’s when the honesty becomes relentless criticism of everything you do that the relationship becomes toxic.
Without trust, a relationship is on shaky foundation. If you don't confide in your friend since you don't think she can keep your updates confidential, you're involved in an unhealthy dynamic.
