Dog weddings are weird, regardless if they had puppies or not.
For humans, weddings can be weird, depending on the circumstances. Having a child to "make it work" is a recipe for disaster.
Planning and financial preparation is never a bad thing, in addition to talking through parenting style a priori in order to talk through differences in philosophy (although I admit things can change over time).
I am a stray human who was adopted as a baby. Hectic circumstances, but anyway I advocate for adoption. That being said, Mr./Mrs. Garrison on South Park made me laugh when they said, "I don't want that fuck trash!" Then I felt sad. But then I felt happy later.
Full disclosure: I do not have any kids. I do not have a wife, ex-wife, girlfriend, or any prospects whatsoever.
