Thanks guys and gals for all the advice here.

My biggest point is my current gf's lack of sex drive. She is just not very interested in it. I think sexual compatibility is very important in a relationship, and I don't know why I took 4 years before really thinking very hard about it.

Perhaps I was in the comfort zone during these 4 years and I thought she would change for the better (sexually) after marriage. We discussed deeply about this before, about my wishes and how I hope we can try to mutually satisfy one another. However, the more I think about it, the more I conclude that things won't improve.

This is one of life's most difficult decisions
