Goras are human beings too. I have not had the opportunity to live in their society, but having watched countless movies and tv serials, I have an opinion that their society has a brighter side too. Of course Rehman Bhai is going to disagree with me ...!
From what I have observed, they keep their relationships alive. Cheating is one of the biggest taboos in their society. They try to get away from their routine lives, and spend quality time together. They have hobbies and they find time to keep their spirit alive.
Of course, my wishes are with you for a very happy marital life. Just that a bit of advice from an elder brother sometimes bear fruit. The key to success is open communication, equality, understanding each other, etc. ... it is a long list. However, the main point is that you should both understand that the possibility of loss of love is there, and that you should both work on keeping your love alive.
