babies

Abigail
In my mind having a baby was always told to me as the worst thing that could happen to you. The normal christian parents have kids when your married gig. But how to you transition from thinking youget pregnant   and the world ends to having a happy mind set for children?? 
Im not pregnant but its effecting my relationship with my bf. I want kids, and i want to be a mom. But i feel like if we ever got pregnant i just need to leave him for his good. Sorry for the word vomit.
