in a relationship, is 8 years too big a difference?

It depends how long you've known the guy, and how you bond. I know people that are are 12 years apart.... and they're doing fine! Go get em!

Depends on your maturity level .

And age group . 18 , i think you're fine .

My great grandmother and great grandfather were 13 years apart , so any can be possible , but remember , there's limits .

he has 8 years of relationship expereince, you have 0. Something is WRONG with a dude this age to be trolling for high school girls. beware

I wanna say yes because you're 18 but it really doesn't matter in the long run :)

hell no my parents were that age when they met , 18 years lates therye still going strong

As long as you guys Truly love each other, no.

no my mom is 51 and my dad is 40, so it seems normal to me

It depends on if you have things in common or not...

I dunno, is it? You're the one in the relationship.
