And no, it's not important for me to know them, though, on occasion, he does let me know what I am doing wrong/what is wrong with me.
When I got to know my ex, and when we married, I was a strong CINO (Catholic in name only). He was nothing, religious wise. He went through the sacraments, and became Catholic. We married in a Catholic Church. In my narrow vision of the world, I thought that was enough. It wasn't. Since we never invited God to our wedding (even though we did marry in His house), nor did we invite him into our marriage, we were open game for the evil one. Like the scripture that tells of the foolish man who builds his house on sand so that when the rains came and the streams rose, the house then fell, that was like our marriage (without God in it).
After my divorce, and after becoming what I will call a revert, where I've become very strong about my devotion to my faith, in combination with attaining an annulment, I see things from my past so much clearer. I see who I was, who my ex was, and what type of marriage we had. I am a significantly different person than I was. My ex is still living his very secular life. So with that in mind, my ex's view of me doesn't carry much, if any, weight. Just as someone from our secular would wouldn't as well (i.e. people with a secular world view don't understand chastity, so I'd never seek advice from them about things like pre-marital sex or contraception).
Whenever I need a sounding board about something, I first go to God. Then, if needed, I seek out strong Catholics (or Christians.....I have a good friend who isn't Catholic but has a strong reliance on God) for help/advice. I've learned to not discuss important issues with people who have a secular view of their lives and the world, which would include my ex.
At least now you and I both know the first thing we should do in a relationship, invite God. Thank you so much for sharing that, you have a beautiful way with words. :)
Once a person CHOOSES to no longer love you, you will appear to be the biggest loser to them and have a list of faults a mile long. That list is not important. What is important is that God loves you and that you are pleasing God, not your spouse. You were never put on this earth to please your spouse, you were put on this earth to please God. So, no, what your spouse thinks are your major faults is not important to know.
I would not want to improve to suit his better but instead, to be a better person. Likewise, I have some suggestions for his improvement as well..
