It's always nice to experience your mind mulling the Bible interpretations and trying to arrive back at personal/ pastoral concerns.

But I'm stuck on theological points, before allowing biblical analysis to make contact with my feelings over a possible romantic situation.

John the Baptist called Jesus a "bridegroom" as his first role, and there is extensive talk throughout the OT about God (and gods) as husband. Though Christian tradition is mystified by those references I see them as the key to the Bible. All marital references, including "one flesh"/"one body" and all the divorce stuff, refers to the divine marriage of heaven & earth.

Where is "cheating" a concept even found in the Bible?

Did Moses, Abraham, Jacob, David, Saul, Solomon etc. "cheat" by having wives & concubines?

I'm not saying feelings from "cheated on" spouses aren't important concerns, but how does one arrive at using the Bible to discuss them?

And as I often try to point out, early Christians seem to typically have been slaves, who had no legal rights, were not legal persons and could be used sexually at will. To focus on spousal situations as an imagined Christian practice disenfranchises enslaved people from spirituality.
