Recently, my wife took her own life after a long struggle with major depression and other psychological issues. When we started dating, I saw clearly that she had issues although they were not as bad at the time. She was also intelligent, beautiful, and ambitious -- among other good qualities. At the time, I thought she could work through her psychological issues with support, and she did improve for a while. However, after her loss, I've decided that, when and if I'm to the point where I'm interested in dating again, I will avoid becoming involved with women who display clear psychological problems. This decision has forced me to wonder if it was a mistake to become involved with my wife in the first place. So is it a mistake to enter into a serious relationship, knowing that the person has serious psychological struggles?
