Evaluate your friendship.

At the heart of a great, true friendship is honesty, compassion, and the ability to respect one another's differences. If those traits are foreign to your friendship, it's time to reconsider why you call this person a "friend."

In a few short months, my ex-friend and I were friends, I went through a whirlwind of emotions. It seems at every corner in our friendship was some small argument that she never truly wanted to sit down and resolve; this would often be why our arguments lasted for so long. I'd always ask if she was okay, and she would reply with a very passive-aggressive, "I'm fine." The biggest lesson I learned from those situations is that you can't force someone to be open and honest about their feelings - they have to come to you.

It's never too late to say sorry

Don't be afraid to apologize if you feel you did or said something wrong. No one likes to be around mean-spirited people, but I think there's an even larger number of people that dislike hanging out with someone who can't admit their faults or like to play the Blame Game. Of course, I was the cause of a fight or two (I'm only human!), but I would also admit to my faults and make the effort to apologize. However, my sincere apologies were often met with a less-than-stellar, "it's okay", that was basically always the end of that conversation about the argument. I’m a firm believer in being the bigger person, and reaching out with an explanation and an apology (which can be difficult if the person involved is very...unreceptive); yet, one person apologizing about a dual-issue can only be so effective. Safe to say, it was a bit frustrating.

Talk it out

If your friend (or former friend) has done or said something that upset you, tell him/her what it was that bothered you and explain why; or, encourage them to do so if it's the other way around. No one likes the silent treatment (leave that to the five-year-olds). I think it's totally valid to harbor a bit of anger if you just had a fight with your buddy, but if it's two weeks later and you still can't find it in you to speak your truth, I would suggest working on your communication skills. One thing that's definitely not valid is pretending the issue never existed by acting like your friend (or foe, I guess in her mind) doesn't exist. It's not cool, in fact, it's even a tad bit juvenile. All in all, some habits should be left in high school.
