Congrats on your pregnancy.
My now almost hubby and I were on the verge of breaking up when I found out I was pregnant. We decided to stay together and give it a go, and I won't lie to you, it was hard! Especially when our DD was a baby, and he didn't understand that I was tired all the time etc..... Anyway, we're getting married in a few months and our relationship for the past 18months or so has been better than ever. My advice is stick with it!
