Why do wife want to come back after willful desertion?

my dear friend,

this used to happen when there was saying "ki raja maharaja bhi ghar mein behayin betiyaan nahin rakh sakte" (even kings can not keep their married daughters home).

but now time has changed, infact girl's parents are the main reason in majority of broken marriage today (and thats the recent announcement made by High Court). 

Mr. Rajendra Kumar the points which you have raised are true. But I think the 3rd point should be on top. As its the main cause. Mr. desertedhusband is also right

If your fighting well then she wants to come for crack the plan.

and resume after some time with solid proofs of cruelty on her,to gather the salary slip, banks account info and other important things that can be used in trail,

This is the 5th reason in addition your 4.In my case it occur..

or she may be back with some packages that suits husband but forgot to deliver at the time of dessertion in hurry!
