Not if that's what works for you!
My grandparents lived in different houses in different cities, communicated via phone mostly and had nothing but love for each other. They considered themselves very happily married, just wanted to do their own thing; and neither of them were seeing anyone else.
That's a pretty extreme example and it certainly wouldn't work for me or fit my expectations in a relationship, but every relationship is different and no one has the right to judge.
