Which actions will best a relationship survive a conflict

 Become mindful of your nonverbal communication. 
Because much of communication is nonverbal, be aware of your facial expressions, hand gestures, and body language to ensure you are sending the message that you want to be received.Avoid behaviors that add fuel to the fire. Physical or verbal abuse is never acceptable.Reflect empathy. 
The ability to show you understand how the other person feels is perhaps the single most powerful communication skill. It allows the person to feel heard and diffuses conflict. You do not have to agree with their perspective, but you can show you understand their feelings (i.e., “I can understand that you felt upset by that.Take responsibility for yourself !!
Save everybody time by owning up to your own poor behaviors. This is not a sign of weakness, rather it demonstrates awareness and integrity and will likely expedite successful resolution. Make sincere and timely amends and apologies.
