For me 5 of swords reversed means being hurt and even insulted, feeling like you've been wronged by someone, but eventually you decide to be the bigger person and to keep it to yourself, because you don't think a conflict will bring anything constructive in the situation. I would guess that deep down inside you still feel wronged and like an injustice was done to you by this friend, so you might be a little bit resentful. And the reversed Judgement signifies that inability to move on from that experience. You either need to forgive and forget or just to leave that person behind. However, in order to clear the air, you might need to tell the friend how you really felt.
