In a philosophical or theological sense you may be a Universalist
From the above linked Wikipedia article
Universalism is a theological and philosophical concept that some
ideas have universal application or applicability. A
community that calls itself universalist may emphasize the universal
principles of most religions, and accept others in an inclusive
manner. It is centered around the belief in a universal reconciliation
between humanity and the divine.
However, there seem to be various different kinds of universalism, which does sound like somewhat of a contradiction, but is related to the different theological histories.
What all the religious universalisms have in common seems to be an effort to be inclusive (also of the people who don't belong to the particular 'universal school') But there is also non-religious universalism which sounds like a set of general common conceptions which most people can subscribe to.
Perhaps at a stretch it could include your beliefs on human attraction not requiring rituals and papers.
Again from that Wikipedia article: a commentary on non-religious universalism
Indeed, many Universalists may be attracted to the logic of
universally applicable principles, rather than any belief or dogma.
Human unity, solidarity, and the perceived need for a sustainable and
socially conscious global order are among the tendencies of
non-religious Universalist thought.
But it sounds like you do believe in some manner of spirituality. Perhaps your world view has similariteis with the Unitarian Universalists.
Unitarian Universalism (UU) is a theologically liberal religion
characterized by a "free and responsible search for truth and
meaning".Unitarian Universalists do not share a creed; rather,
they are unified by their shared search for spiritual growth and by
the understanding that an individual's theology is a result of that
search and not a result of obedience to an authoritarian requirement.
Unitarian Universalists draw from all major world religions and
many different theological sources and have a wide range of beliefs
