I saw your comment on the Happy Anniversary post, and wanted to comment on your questions here, so that others could sound off on their opinions for any challenges faced in the first year, if any. Congrats to you and your new marriage, by the way!
Patience and open communication has been a major key for us to get through the little struggles that have popped up.
The first year is different for everyone, and depends upon where you and your husband are coming from. For us we didn't have many challenges, then we decided to add a puppy to our home, raising her from 6 1/2 weeks. We got our puppy 6 months into our marriage, and we've actual had many disagreements since getting her, more than we ever had in our entire relationship of nearly 5 years. But we have learned so much about each other, and we got through all those stresses that come with raising a puppy, and other issues that came up. My job I recently got laid off from also made for struggles, including the emotional stress of getting laid off-good ridance anyway with that company. Dh was understanding, and my rock, and I reminded him how much I appreciated him for being patient with me and my emotional outbursts.
No matter the issues and struggles that have come up, the biggest thing is our marriage, and how we are more in love even now then we were when we married, and doing all we can to maintain that love still shows and grows to carry us through everything that we are to face.
Hope that helps!
