It is bizarre, and incompatible with Torah, to proclaim that there is a mitzvah to enter a bad marriage. It is similarly blasphemous to blame this on the mitzvah of pru urevu. There are so many clear references in Torah that a marriage is intended to be a loving relationship that denying that is either foolish, or borders on apikorsus.
Let’s begin with Yitzchok Avinu – ויאהבה. Shall we continue with ושמח את אשתו. The metaphor for אהבת השם is אהבת איש ואשתו as per שיר השירים. Shas is replete with open references to this relationship. אהרן הכהן was busy with being אוהב שלום with specific reference to בין איש לאשתו. A relationship lacking this is not the Torah model.
We all understand that some marriages are not ideal. But to proactively push someone into such a situation is cruel, and has no Torah position in its defense.
