Friends tend to choose sides in a divorce.
After a death family and friends, not knowing what to say or how to deal with the obvious grief of the person left behind, tend to avoid them. This is a time when support is essential and isolation intensifies and lengthens the grief process. Joint married friends drift away because the glue that created commonality and connection disintegrates between them and the single person as lifestyles change and take off in different directions. This change process leaves many singles with major holes in their lives which must be filled in some other way. Many singles become overwhelmed with this process, not knowing even where to start.
