Answer:
From what I can conclude, this paragraph seems to be speaking of some character to another character, whose name is Gawaine. This character, Gawaine, must have betrayed the other character in some way and will no longer be amended by the court. I am not sure what "the court" is referring to, whether it be a wedding or something referring to government, but there is definitely deeper meaning there. Yet, due to the speech and words such as "ye" being used, it seems to be set far back in the past, so the court may mean something from many years ago. Also, the other character tells Gawaine: "ye will never be sorry for me as I am for you”. This probably means that Gawaine did something terrible, but whatever they did affected the other character even more and they feel sorry for what the consequences of what Gawain's actions are. This is what I can conclude from that part of the conversation given.
I hope that helps!
