All couples experience conflict. Most of these conflicts can be resolved, I believe, and I would mistrust any so-called science that seems to rob you of hope for harmony or aggravate conflicts between you and anyone you choose to love. I would not let socionics make you worry about you and your husband if I were you. You have creativity and affection enough to resolve almost any conflict with him that you feel a need to resolve.
Psychosocial sciences are probably not advanced enough to decide whether a relationship is a dead end, unless violence recurs — in which case, you don't need science to tell you the obvious. Only you can make those decisions. Yet the jewelry and roses are good indicators that the relationship still rolls onward, wouldn't you say?
RE: Socionics - is it help or is it harm??
