“Relationships can be wonderful but challenging under the best of circumstances. When one partner has a serious mental illness, the situation can become even more complex. Many times, the partner without a diagnosed disorder will assume more responsibilities, at least for the short term. For a person who is already worried about what is happening with his or her partner, having to spend more time maintaining the household or taking care of the children can be especially hard.
It is important for the couple to keep in mind that most people diagnosed with a serious mental illness improve over time, and that a partner’s attitude and behavior can make an important contribution to recovery. It helps to maintain an accepting and positive attitude, while holding realistic expectations for the partner with serious mental illness.” Source: http://www.apa.org/helpcenter/serious-mental-illness.aspx
