What's the best dating advice you have?

Good afternoon!

I will have a date with a guy this Saturday.
You know I love him,but he didn't know it yet.
Do you think I should let him know this on that day?

And how can I let him know? 

I have no ideal now,could you help me??????

as he will run or either it will make his ego grow so big that he might treat you as an easy catch

wait until he tells you that he is intersted in you , he might say he likes you or he loves you ...so just wait for him to reveal his feelings for you

I don't mean to be a dampener, but how did you fall in love with him when this is your first ever date with him? Are you guys at least friends or have known each other for a significant amount of time?

My advice would be ... NO, I don't think you should throw the love word this early, much less saying that out loud to him on your first date. We don't have an idea on where he stands. Just focus on making sure the first date goes smoothly for now and see how things unfold. Save the love discussion for later after you start feeling something from his side as well. 

Good luck.
