Marriage will always be between two sinners who cannot make the other person totally happy in this life. It is about two people helping each other through this life on the path to Heaven, along with their children. That requires a sacrifice of self in order to serve the other. These people who fear future marriage because of issues and what have you, as well as these books that tell you to watch out for this and watch out for that, don't seem to understand that they are doing a disservice by giving people a false impression that they can find someone who will never hurt them.
Just because a person makes a choice in marriage and it does not work out as they had hoped, it does not mean they failed at marriage, nor that there really is no marriage. It just means that their marriage is what it is, and you have to work very hard to do your part, and pray very hard the other will do their part to strengthen the marriage and make it better. That is what love is.
Okay, so some marriages don't have the blissful feelings of love they once had or that are desired. Does that mean single people should keep putting off marriage because they need to ensure they will always have that? No!
Marriage is a total risk! So if you are not up for the risk, then never marry. But don't fool yourself into thinking you can avoid a bad marriage because you do all this analysis and inspection.

Don't listen to the advice that says to avoid a person whose parents are divorced. That's nonsense. God's grace does wonders to help any person who is walking the path of God. It is a person who relies on God's grace that you want to marry, despite their background. Then you have a person who can not only overcome their past, but someone who is really going places, and capable of moving mountains. And certainly a person who will know how to love.
Yes, you have to do some due diligence to see if the person's issues are unresolved to the point of making them incapable of marriage. But that means it has to be serious, and it will be, obviously. Again, the key to a great marriage is when both people know their own weaknesses, faults, past issues, etc., and that they accept each other's weaknesses, faults, past issues, etc. Then they can really be an exceptional "helpmate."
But because people are human beings, and human beings are always growing and changing, no one should enter marriage with the expectation that a person is always going to remain as they are, or (God forbid) make them happy at all times.
So take from the book only what makes sense, and never let anything make you feel uneasy. As far as bringing up the subject of divorce, I don't see why not. If you want a good "in" to talk about it, just say you were reading the book and noticed that it talks about divorce in one's background, and ask what he thinks about it and what he thinks about your having divorced parents. He should be sensible enough not to discount you because your parents are divorced. But it is a good conversation to have.
