Everyone have their own life. Wedding itself I think of it as celebration but remember not to spend too much which cause you in debt. You must manage it with your fiancée so that you won't exceed your Budget. Once you got your Budget out and plan out well, celebrate with a carefree attitude.

I would suggest you jump ship because based on your qualification you can get a better annual package, however there is always a risk in every jump which is the uncertainty of what's coming up next, the environment, the staff and etc.

I am around your age, this year 28. I am happy with my salary and also I try to earn some passive income like bank interest (ard $150 per month) and dividends (ard $20 per month). So there are many ways you can boost your income, like some rent out properties or investment in shares to get dividends and etc. So do not stress yourself too much
