Yes, without knowing your age it's hard to say. First, I hope you're both over eighteen or under eighteen. Otherwise, you could be headed for more romance than either of you wants:
Law enforcement is getting serious about prosecuting those in some areas.
Secondly, I have seen relationships with tremendous age differences blossom. I've also seen them crash and burn. Age isn't just a number. I deal with a whole different set of challenges in my forties than I did in my twenties. I also have a different perspective. One thing that generally comes up is that people in different age brackets enjoy different things. People in their twenties want to cruise the strip, run around with friends, go to the local fair, etc. When you're in your forties, it's often kind of "been there done that." It's more important to consider whether your interests and values and compatible than to look at the number value. I know an extremely happy couple, man in early 70's woman in mid 50's that are extremely happy. I think general compatibility is more of an issue than the number you get when you subtract one age from another.
