Are we an ideal couple?

What do you think of a couple that dated for 8 years?
Family and friends tend to think we are perfect for each other
I had friends that dated for more than 10 years and broke up in the end
Do they have the similar relationship problems as mine?

Girls always have a lot of emotions
Sometimes I would love to be loved
Sometimes I would like to be alone
Sometimes I want to do whatever I wanna do
But I can't.. because I think of you..
