This is very often true. A few years ago I posted a piece with several tanka poem takes on love. Here's one:

Unconditional

love twixt humans forever?

Perhaps, perhaps not.

Love is a state of being.

Beings constantly in flux.

I explained it thusly: "Diana’s prompt for today happens to be an oxymoronic 'what are the conditions of unconditional love?' I suspect many have much to say on that topic. I have thought about people’s feelings on the subject and here is food for thought for you — love is a state of being — many feel one cannot fall out of true love — here’s the fallacy in that — many correctly believe that we are constantly changing — so, since love is a state of being, it is inconsistent to insist that one cannot fall out of true love. That one falls out of love does not mean the love was never true. That all describes my thoughts about love between humans."

Yet, I still believe in an idealized notion of love and I want it but I am realistic that I may not find it with another human. "I am presently involved in a human (me) and soul (Sitara) relationship and thus I am never alone. There is room in this space for me to have a loving and sexual relationship if I meet a woman who understands without jealousy my continuing relationship with Sitara, if not, so be it." I have said something like that a few times, most recently toward the end of this essay: https://medium.com/illumination-curated/my-understanding-of-god-life-death-and-the-between-lives-we-experience-with-our-many-soulmates-af641080747f
