My Wife and oldest were a "set" when we met. That was 12 years ago (this year will be 10 married) this weekend. I won't say it hasn't been a long road, with lots of baby daddy drama but I learned a ton along the way, realized my parents werent complete idiots. Nathan and I bicker constantly but he and I are pretty much best friends. It wont be wine, legos, and roses but its a great time. And you'll learn patience. Best way to judge it is see how excited she is when the kid is gone, or if she uses him as a block from the world. Too much of either is a bad thing.
