Just thought this would be a good subject and helpful to some. Thoughts?
Not enough sex
Never been married before, but communication/trust usually plays an important role in any successful relationship.
Dan the Man said it-I can't improve on that.
I agree that the reasons are quite varied. One reason, for me, that marriages, relationships of any kind, flounder . . . When one or both parties use the "kitchen-sinking it" mentality to expel all their hurt and anger from past problems and issues, packing them all into a current one. I think that creates a ready-and-able breeding ground for hostility and does nothing more than widen the chasm the couple is experiencing.

I don't know about most... but sometimes people tend to preoccupy themselves so much with activities that they forget who the most important people are to them... and then the distance grows as the communication becomes lacking more and more... until it finally reaches a point where they are just passing friends living in the same house.. The "we" becomes "he" and "she" on a consistent basis and then finally it gets to a point where you realize it's beyond the point of being able to patch up... because even if you start talking... and listening... the past still is a part of the present... and some things are just too difficult to overlook... even if we make the effort to try... we can only try so much before we have to give up.
