>>5707976A friend treats another friend with respect and love. Take a moment and consider if your friend is really ignoring you, or just busy. Ignoring somebody hurts them emotionally. Intentionally ignoring your friend because you're mad at them over a disagreement is not something a friend would do.
OP, if you think this person is ignoring you because they're mad at you, you need take a step back and reevaluate your relationship with this friend. Is it possible that you value the friendship more than this other person? Are you creating uneven expectations in the relationship? Would the energy that you're putting into this relationship be better spent strengthening other relationships in your life?
These are all important questions you should be asking yourself.
