Uff man you've got to go right now to the Amazon store and buy Jason Evert's "The Dating Blueprint" 🙌🏼. There are tons of 'Dating advice' books out there that give you the same worn out "groom and be yourself" speech. Jason Evert was a surprising find for me, as I couldn't help but feeling I was reading something fresh. He's 100% Catholic, all the advice he gives is given through the Theology of the Body perspective, and he also interviewed a lot of women for his book on what works and what doesn't work for them when going out with Catholic guys. He even has a small section at the end on the ups and downs the married life poses (that no other 'dating guru' will mention).
I'd suggest you to get Jason Evert's "The Dating Blueprint". Maybe you've heard of him, he is Catholic and gives Theology of the Body conferences across the country. His book honestly surprised me a lot, he walks you through the dating process through a 100% Catholic perspective, and he actually surveyed a ton of Catholic girls before writing the book. So the advice you get is great.
