In all honesty, I think the only person who can truly love is Jesus. Everyone else will fall miserably short sooner or later. The only love that will last is the love that God works into our hearts for others, but it may take many years for this to be developed. I even wonder if we will not be able to bear the fullness of it until we have been completely changed into His image.
I see marriage on this earth as an object lesson concerning the true marriage that God desires for the Lamb and His wife. I think that marriage in this life is built up by the media and by many in the church as the ultimate experience. If the Lord loves you and wants you for Himself, He may not allow you to have the "ultimate experience" in this world because He Himself wants to be that in your life. That does not mean He won't let you marry, but He may ensure that He is always first in your life by giving you a wife/husband who does not meet your needs to some or any degree. I know this is probably a very unusual idea, but unfortunately to look at marriage in this world as any more than a duty, is to set ourselves up for disappointment. If we end up with a happy marriage, that is great. If we end up with a miserable marriage in spite of everything we may have done to make sure we would have a happy one, then it is apparently God's will make our marriage our cross, in order that we will make Him our all in all.
In many cultures, the wife is thankful for her husband because without him she could not have children. He is little more to her than the father of her children and the provider, while she is the household servant. This is perhaps a very rudimentary view of marriage and certainly not the western ideal or the Bible model.
Romance is all well and good, but the truth is that marriage and family life is very hard work. Providing for a family and taking care of all the daily household tasks for any number of children, is a tremendous committment, taking all the time and energy of both parents. When there are financial or health issues, it is even more difficult. Marriage in this world tests and tries us. It is a picture of the ideal, although in this world it can never be ideal (unless someone is exceptionally blessed with a great many advantages).
In this world, love is much more of a committment than a feeling. Maybe if marriage were presented in a different way, more as something done out of obedience to God than as a way to happiness, there would be less divorces.
To balance all of this, I will say that God's love is the most amazing thing in the world (I have had a brief experience of it) and will be well worth it. Another treasure in Heaven...
After all my blabbing...maybe what I am trying to say is that our "romance" should be with Jesus, although we are commanded to love one another in our various relationships.
