In age between you and your partner? How old were you both when you were first together?
DH and I are 11 years a part in age. Generally, it doesn't affect us. Mostly the difference is in our friends. This is a second marriage for both of us and his friends have older kids, mine have younger kids. Together we have been making friends with lots of kids, so it's all good!
if you have a big age difference, how does it affect you?
