Was Martin Luther's marriage to Katharina von Bora due to their love for each other?

The documentary series *This Changed Everything: 500 Years of the Reformation* includes a section in episode 1 about Martin Luther's marriage to Katharina von Bora. Dr. Frank James (President and Professor of Historical Theology at the Biblical Theological Seminary) includes his input as well, and says that it was due to their love for each other. > Narrator: Martin Luther turned the idea of marriage on its head when he married a runaway nun, Katharina von Bora. In a society that views marriage as a financial and social contract, Luther's marriage is revolutionary. > > Dr. James: Well, there was no social status to be gained for the two of them getting married, and there was no money. I mean, he didn't have any money, and she didn't have any money. So what did they have? They had love. […] Before it was based on social status and a dowry. Suddenly, this whole notion of marrying someone because you love them becomes a significant paradigm shift in the concept of marriage. This is in contrast to the Wikipedia page of Katharina von Bora , which states that Luther arranged marriages for runaway nuns like her so that they could be provided for > Luther at first asked the parents and relations of the refugee nuns to admit them again into their houses, but they declined to receive them, possibly as this was participating in a crime under canon law. Within two years, Luther was able to arrange homes, marriages, or employment for all of the escaped nuns—except for Katharina. […] > > Katharina had a number of suitors, including Wittenberg University alumnus Jerome (Hieronymus) Baumgärtner (1498–1565) of Nuremberg and a pastor, Kaspar Glatz of Orlamünde. None of the proposed matches resulted in marriage. She told Luther’s friend and fellow reformer, Nikolaus von Amsdorf, that she would be willing to marry only Luther or von Amsdorf himself. While it's clear that Katharina stated her desire to marry Luther, it's not clear to me that the two chose to marry out of mutual love for each other (in other words, it wasn't a love marriage ). Which account is correct? Was Martin Luther's marriage to Katharina von Bora due to their love for each other?
