Marriage and weddings are irrelevant. Kids change everything. If you really truly love your partner and potential in laws warts n all you can survive and thrive. If you don't then don't get married or have kids. Also spend next six months deeply studying child birth, rearing, financing, illness, disability, etc etc etc before having kids. And read real news sites regularly. Wake up basically.
I'd actually suggest going to joint relationship therapy before getting married and work out exactly your hopes and dreams and fears and plans with a marriage counsellor. Pay decent money. You might discover you really don't want to commit for kids/life. Or that your are a good match.
If you are religious just don't put your trust in God etc. Think before you get married. Really think!
It's your life. What do you want.
Really ****ing think!
