Loneliness is more of a symptom than a cause. Rooted in the unhappiness they feel in the MR. I've never heard a spouse, regardless of their childhood, saying hey are "lonely" with in a happy, healthy MR. So no, I don't think it has to be addressed, I think it is naturally alleviated as the R unfolds.
