Is it a silly question? "Those words are very strong and meaningful," were
your words. I don’t think you take this topic silly. For what it’s worth, in my
opinion I don’t think you believe is silly at all. Why do you think saying I love you is meaningful? That is more for you to answer to yourself.
 
Lust, love, and long-term relationships are three very different things requiring different
skills, with some overlap.
 
Lust and love more or less ‘comes’ or ‘happens’ to you. Long-term relationships are
more work.
 
Expressing what you want to express is another way of saying you’re vulnerable when saying
I love you. Do you feel comfortable being vulnerable around her?
 
It’s been about 6 weeks, correct? Have you two gone out of your element? Or to think
of another way, is your environment with her routine, safe, and ‘normal’? Advice
I came across awhile back was while in a new relationship do something new. Travel,
go to a different club/event (whatever, idk what you’re into but get out of
your element) to stress your relationship to see if it’ll work.
 
You’ll know after the ‘stress’ if it’ll be worth vulnerability.
 
I’m trying not to give advice. I’m trying to have you think crucially and critically.
I hope I was successful.
 
Good luck to you.
