My 2 cents here as a husband and a father ....

* sit down with her and work out your wife-and-husband life journey (what both of you plan to do, work, income, holidays, kids, etc etc etc).

* forecast your $ needs (house, car, holidays, kids, etc) and see if you have enough. Adjust if possible to suit. Need both parties to agree on the sacrifices. Write these down and keep it.

* need money for the marriage life. BUT that is only a part of a happy, successful, rewarding, peaceful, satisfying marriage. Answer these 2 questions - why do you want to get married now? Why do you think she will fill that void in your life?

* similar character, likes and dislikes? Don't expect her to change to your way after marriage. Small differences which both of you can accommodate now as BF & GF but the same small differences can ignite arguments in marriage life!

All the best to your new life chapter!
