I wish I knew how hard it was going to be to step into a pre-existing family and take on stepchildren that were older. Just the challenges that you face trying to be a parent to them and a partner to your spouse and the delicate balance that you walk between the two.
Something I wish I knew is I didn't have to figure it all out before we were married. We've learned a lot since we've been married over these years and I put so much pressure on myself for not having this figured out or not having a solution to this problem, but it gave us opportunities within our marriage as husband and wife to get those solutions together.
I wish I knew that marriage is more than just butterflies and rainbows, but it does take effort on both sides. I kind of knew that, but it's been good learning, good learning experience.
