Nope, mutual attraction is what couples need. People invent unsolvable problems in their relationship when they lose attraction.
My own experience after 15 years of marriage is that attraction comes and goes for both me and my wife. But by not doing anything rash when that happens we have both discovered that it also comes back. Sure the first few times it happened it was quite scary, but then we've found a rhythm with the ebbs and floods.
If you are just waiting for the attraction to come back, chances are that it doesn't, even though it certainly could. It all depends on the reason that attraction disappears. Sometimes it's related to the things you do and sometimes it isn't. The key, I believe, is to always try to be a better spouse than you were a year ago, or even a month ago. But that of course presupposes that there exist mutual trust and respect between you. It won't work if only one part is trying to be a better self for the other.
My physical attraction to my wife comes and goes. When that first started happening, it was traumatic. At this point, it really doesn't feel like a big deal. There are always more important things to be working on when it happens. (Probably not coincidentally!)
A bit later in our relationship, the same thing started happening for more general attraction. The decision to stay together would get very practical for a time. Again, this was initially very traumatic, but over time it became more and more clear that it was an effect, not a cause. Our focus shifted to the true causes, to the extent we could figure them out, and that was vastly more effective than trying to somehow address lack of attraction directly.
In short, my experience directly contradicts your position, anecdotal though it may be.
Attachment Theory attempts to explain why certain relationships are better than others which is dependent on how secure or insecure each partner is with regard to attachment. For example, if both parties are classified as having “secure attachment”, they may feel distress when their partner leaves them for say a long work trip but they’re able to compose themselves and control those worries. That sort of relationship would be said to have a higher chance of survival than two partners who are both “anxious-ambivalent attached” because in this case, the parties would instead have strong fear or worry of rejection by their partner, higher dependency on each other, and less likely to be comfortable being alone. None of those elements rest solely on the basis of attraction. This type of behavior stems from being a witness to conflicting figures in their life (e.g. divorced parents, unsafe family habitat, etc.)
Even with your definition of attraction, attraction-based love is fundamentally self-serving, and those who practice it rob themselves of the beauty of blind commitment in loving relationships.
Why do people bother dating if it’s sufficient to move in with a friend?
How do we explain people who already live with close friends and are also out seeking romantic partners? What marginal benefit could they be looking for? Why limit the search according to gender, if attraction is not essential?
