Well, in the objective sense, you have to base a marriage on friendship and that friendship would gain colour from whatever chemistry existed between the persons. I suppose if there is a friendship, there is a will to keep going together and so there’s the desire to keep up the chemistry instead of focusing on self-pity when it seems to wane while not being consciously supported. So, say, you have two people who are good friends, see value in each other, want to give themselves to each other, have feelings and desire for each other, they will make and constantly affirm and live the decision to be with each other, giving up and throwing away all alternatives (other people, singleness), putting their all in their relationship, then I don’t think they should have problems with chemistry and electricity. On the other hand, I wouldn’t expect chemistry and electricity to last forever on their own fuel. There are various theories about how long attraction/falling-in-love lasts, more or less anything from 0.5 to 2 years. One of the theories I’ve read about says 2 years but possible to have again with the same person. So basically if circumstances are created in which you can’t really not fall again for the same person (such as a loving, supportive, integrated marriage), I suppose there would be falling in love again and again, although in different ways and not always in reaction to the same factors. Obviously, this is theory and ideal, in reality there will often be problems, but when there’s the decision to stay together through good and bad, those problems shouldn’t tear the couple apart even though there might be little feelings or attraction or anything at a given moment. Also, there’s no denying that attraction is a problem for couples quite often. My father would reply to this that you still need to court the woman as if she were a girl you dated even when you’ve been married to her for long. You just need to keep trying. The same goes for the other person… so find someone with similar ideals, who believes in not letting go? Besides, things look different when you’re 20 and so than they are when the woman has had a couple of babies and the man has a bit of a belly and is balding… and they’re still attracted to each other, sometimes quite strongly. Well, I’d be willing to credit friendship with the good things because friendship tends to deny egoism and romantic love doesn’t always. Thus a person being friends with his or her spouse will probably try to make it easy on the spouse and cooperate instead of just waiting to get his rights fulfilled and resigning himself or herself to getting the duties done, while not wanting to go much beyond… in which latter case no one will be happy. So what you seek would require effort and motivation for that effort would come from friendship, I believe (friendship not implying reduction of the electricity or chemistry

).
