Why many couples are separated?

I think it's because they never stick to their commitment. I believe that feelings may come and go. If a person depends always depends in his/her feelings I don't think he can be a good husband or wife.

It is very disappointing whenever couples separate because it is something both have never dreamed of but circumstances force them to take this severe step. there might be several reason for this like lack of compatibility or comfort level or understanding between each other that might have forced them to part ways.
