I think we've all probably been too enthusiastic/eager in the past and its ruined her attraction

However, the opposite end is being too casual and low-key, which makes you seem uninterested or boring.

Where do you guys find the balance?

For example, this was a text exchange I had today:

her: Hey {name}, hope you're having a good day. I checked the weather and its bad all day. Do you want to meet tomorrow instead? It's looks nicer

me: Hey hope you are too. That sounds better to me, does 2pm work?

her: perfect! Thank you! See you tomorrow :)

me *hearts her message*

me: Awesome see you then

My personal impulse would be that this response of mine might come across as too unfriendly or casual, but at the same time, I also know you can really turn women off by seeming too eager and so I've been purposely scaling it back

How do you all handle this?
