<human>: We live in different countries in Europe, met through a video game. He visited me this Summer, he'll be visiting in December too.

He's a great guy, he's extremely caring and protective (though very jealous too), he's got a great humour and he's **always** there for me when I need him. He's got trouble with anger, but he's great at putting things behind him once they're solved.

Even though we're almost opposites, we compliment eachother very well.

That said, I feel really weird about the age difference, even though it's legal where we live. I had a weird feeling about it from the start, I couldn't imagine an 18 year old being interested in a 15 year old for anything besides sex.

Everyone else is (seems to be) okay with it. My parents don't mind, his parents don't mind, my friends don't mind, his friends don't mind. He doesn't mind. But I cannot help but feel bothered about it. I see a lot of comments on this sub about age differences, and even though ours won't be big at all in the future (if we get there), I feel like it's a problem right now. I'm 15, I'm still a child. He's an adult. 

When dating younger they say you can safely date someone half your age+7 years. He's 18, half is 9, add 7 and he should be dating someone 16 years or older. I'll be 16 in less than a month, but I still feel weirdly guilty about it. 

I'd appreciate some older and more mature peoples opinions on this. Are my thoughts justified? Should I just roll with it?

Can you summarize the given text in a few sentences?
<bot>: 15 year old girl with 18 year old MAN, feels weird about the age difference. What do? (if anything at all?)
