Pregnancy can be so transformative; changing everything from your body to the way your brain works to what kind of person you are and who you want to be. It can be amazing, horrible, exciting, scary, intense, delightful, sad, and hilarious all at the same time. It can teach you what you are and are not capable of, and it teaches you many of these things about your partner and your relationship, too. In my experience, there are definitely things you can only learn about your marriage during a pregnancy.
During my first two pregnancies, I learned so much about my now ex-husband. Mostly not good. Would he be OK with not having sex as frequently? Nope. Was he interested in learning how to perform basic parenting tasks? Nope. Was he a self-absorbed person who prioritized looks and outward appearances over a healthy, stable relationship and home? Sadly, yes. These things (and much more) became clear and, ultimately, were things we weren't able to overcome. I now know that learning these things about my partner and our relationship was actually pretty important. Rather than bringing us together, though, pregnancy pushed us apart.
Now, that I am re-married and pregnant again, I have again learned so much about my husband and our relationship; mostly good this time. We've had to overcome some pretty stressful and scary situations, some pretty gross moments, and some pretty silly arguments. Most importantly, I have seen him step up and keep our marriage and our family running smoothly, when I wasn't able to contribute at the same level as before. He's made me feel great about my changing body, and he's shown me moments of pure love involving vomit and other bodily fluids. Ultimately, I have learned that I can count on him, and it has brought us closer than I ever imagined.
