I think I'm falling in love with a guy I met online. He's 8 years older than me.
Why are you falling in love with him specifically?
I don't know, but I'm definitely falling in love with him.
There's nothing wrong with loving someone you met online, even if they're older. As long as you aren't a minor it's okay.
But he's 8 years older than me. What do you think about that?
I think if you aren't a minor, it's okay. You should think about what attracts you to him and why you feel like you're falling in love.
