I would be very suspicious of my son dating a woman that many years older. You are still a very young adult and have a lot of life lessons ahead of you. Please be very careful. Don't allow yourself to be pressured to do anything for love if you are not ready.
My 30 year old brother recently married a love of his life, a woman who is 43. The difference is they are both fully grown and mature adults.
Please, don't do anything before you are ready.
