Birth defects were our big concern. The older the parents get, the more likely birth defects are. We both agreed that we would abort a fetus with major defects. Also, we agreed that we would hide the truth from our Catholic parents if it came to that and claim I had a miscarriage. Thankfully, that wasn't necessary. Our first child is perfect! We want more than one, but not right away. I had gestational diabetes and had to walk after every meal, so in order to do that again, we need to get to a place where we can keep that sort of schedule. Adoption is on the table for the second one since I want a girl, but we're still giving it some time to decide.
We were friends with benefits for most of those years while he was in the Navy. We spent two months together in Hawaii, where I cooked meals for him in a slow cooker to save money. He moved in with me a year and a half later, and then it was about a month before he became my boyfriend, and then we got engaged after another few months.
We've been married for a little over three years now, and things are going well :)
Also, one of the reasons I said yes so quickly was that one of my boyfriends died in 2015.
I'd also like to add that I haven't been in a monogamous relationship since 2008.
