How does "the wife's lament" deal with the experience of loss and pain? of solitude and exile?

Written in the first person, the titular wife begins by saying that her words come from a "deep sadness", which is a result of her exile. she has never experienced hardship like this before. she is tortured by her isolation.
she explains that her misery began when her lord left their family and sailed away, leaving her behind. she was consumed with anxiety about his whereabouts. taking action, she decided to undertake a quest to find him, setting out as a lonely and "friendless wanderer." however, her lord's kinsmen did not want the couple to be reunited and devised plans to keep them on opposite sides of the "wide world." the continued separation left the wife heartbroken and longing for her husband.
she shares that ultimately, her lord requested her to live with him in a new country. she moved to this strange place where she had no friends, which made her sad and lonely. also, she quickly discovered that her husband had been plotting behind her back. beneath his proclamations of love, "behind [his] smiling face," he was actually planning to commit mortal crimes. she remembers the good times of their marriage, when they had sworn to each other that only death could part them. sadly, she relays, she realized that she could never feel fondness for this man again. their friendship vanished as if it had never existed in the first place.
