I just met a girl and I think I'm in love with her
Why are you falling in love with her?
I'm falling in love because of her personality.
You shouldn't fall in love with someone you just met. You might love her personality now but find out that there are other things you don't like as well.
Nah, love is forever.
Falling in love is sure really great, but don't you think you want to take things slower? You might get your heart broken just as fast, and it won't feel really great. I'm sure she would appreciate the pace as well, so she won't feel pressured into anything.
