My GF is 17 years younger and we hv been a couple for abt two and half years.

Not much problems, shes quite matured for her age and Im quite youthful in my outlook of life. Im the more adventurous, she is the more cautious.

There are many things that we complement each other. But there are some challenges:

Family acceptance: some caution at first (both sides). But got better/acceptance once become everyone more familiar.

Health: the senior partner has to be in good shape. I go to gym 4 times a week and am watchful of my food. Have to maintain this.

Career at different stages. She is still at struggling phase. Im past peak. This is potential area for misunderstanding.
