The Bible forbids neither polygamy, nor widow remarriage.
For the married woman is bound by law to her husband while he is living; but if her husband dies, she is released from the law concerning the husband. So then, if while her husband is living she is joined to another man, she shall be called an adulteress; but if her husband dies, she ...
Christianity forbids polygamy but allows widow remarriage.
I agree with you that Gal 3:28 is not usually cited as support for the rejection of polygamy, because the passage context is about unity of Gentiles and Jews in Christ (notice the contrasts of social groups in the verse). Ken Graham already covered the OT view of polygamy, so I will not repeat it ...
Does Christianity or the Bible forbid polygamy and widow remarriage?

G.K. Chesterton discusses the logical absurdity of pretending to "cancel" a life long vow with a piece of paper from a government in "The Superstition of Divorce". I highly recommend reading or listening to (free on Librivox) this short book.
Disclaimer, I am not Catholic, but try to study their positions seriously. I think a friendly outside perspective ...
One interpretation is that Jesus is speaking to those who are called to preach the gospel. In this case the “left” is in the temporary sense (as in the song “Leaving on a jet plane”). This view is supported by Peter’s statement in verse 28 and in the parallel passages of Matt 19:27 and Mark 10:28. The disciples “left everything while they followed Jesus, ...
I generally like timf's answer. However, I would also add that "leaving one's wife" could also be the equivalent of not getting married. For instance:
