Communicate

• Communication is good for both the healing of the friendship and also for the further prevention of any future overstepping of boundaries. Every situation is different, but making assumptions and jumping to conclusions often play a role in overstepping your boundaries. Take the time to explain where you are coming from. More importantly, listen to what your friend has to say about matters, and learn what she needs from you. Sometimes less is more.
  
  

Make Ammends

• Let your friend know that you are sorry for overstepping your boundaries. If you stubbornly insist that you've done nothing wrong, then the conflict will only continue. This in turn can jeopardize the friendship if it goes on long enough. If you do indeed feel that you were in the right, swallow your pride and at least apologize for them interpreting your actions the way they did. For example, "I meant well, but I'm terribly sorry that what I did made you feel uncomfortable. It wasn't my intention."
  
  

Lay Low

• Time apart can be quite effective when two friends are at odds, especially when she feels that you have overstepped your boundaries. The key is to use the time to understand your friend's point of view and how you can possibly change to avoid unpleasant overstepping in the future. Just make sure that you're laying low out of respect for her and that you're not mad -- you're merely giving her space.
  
  

Consult with Mutual Friends

• While you don't want to bad-mouth your friend, it can help to talk with a mutual friend who doesn't take sides. He's not the one mad at you, so his neutral perspective will make him a great listener. Plus, he may have some effective tips for resolving the issue and avoiding the same situation later since he knows both you and the other friend well.
