Is 10 years difference too much?

I think it depends on the person. I am twenty three and have dated guys younger than me and older. My fiance right now is 42. If you are both attracted, respect one another and click than it doesn't matter as long as you don't feel taken advantage of

Well, if you think of it in terms of say...30 to 40...or 40 to 50...it doesn't seem like such a big number...so no, I personally don't think it is too big of a number...sometimes it just happens..if he makes you happy, why worry about age?

Okay, the younger you are, the bigger that number becomes. Think of it this way. When you were starting middle school, he was starting college. I don't normally have a problem with age gaps in relationships, because I've seen it work, but it really only works when both parties are adults. As in, graduated from high school, moved out of the house, starting their own lives and knowing who they are as people. How do you parents feel about you dating this guy? I'm betting they don't know, and if they do know, they don't like it. You're what, a junior in high school? You're not going to be moving out for a while yet. Whether you like it or not, they still have control over you, and whether you believe it or not, they do know what's best for you.

And the fact that prior to your birthday, he was totally comfortable dating a 16-year-old who DID NOT KNOW HIS REAL AGE, sends up huge red flags for me. He may seem sweet and mature and wonderful, but if that's the case, why is he dating a high school girl? No offense or anything, because I'm sure you're a great person, but don't you find that odd? I feel like he doesn't have the best intentions here, and you need to be extremely careful. If I were you, I'd get out altogether.
