And other facets of the relationship come into the picture. Are there children from a previous relationship? The parents of your partner/spouse utter their comments. Siblings pass judgments.
Certain comments are made by the partner, and certain opinions could be perceived as demeaning or cruel. General disagreements escalate to name-calling and insults ensue.
So where did that passion and longing go? Any or all of these previously-mentioned behavior(s) are red-flags that the relationship is trouble. The relationship is not getting nurtured, and the time and energy is not spent on fixing it.
All of this eat away at a healthy, loving relationship.
