Strain can be placed on a relationship when stressful circumstances affect the couple as a whole, or even just one of the partners. Chronic illness of one person, for example, can impact the well-being of both partners. Many couples struggle with communicating effectively and feeling that they are heard by their partners, as well as differences in parenting, political views, or expectations. Severe stressors include infidelity, terminal illness of one partner, and serious mental health issues. Resentment, contempt, and an increase in the frequency of arguments tend to be signs of underlying problems that have been left unaddressed.
Some common relationship concerns include financial difficulties, barriers to communication, routine conflict, emotional distance, sexual intimacy issues, and lack of trust. Sometimes, marriage itself can be the issue at hand for unmarried couple, when one partner wants to marry, or is subject to social or familial pressure to do so, and the other partner is reluctant or feels unready to marry. Couples who are considering marriage may seek premarital counseling for these and other issues.
