You work on yourself first, then date. That's for her to figure out. No one owes miserable people a chance. I'm not sure why you're suggesting lying is acceptable just so she can date. Weird opinion.
The choice is yours!
You dress up for interviews, more than you would to go get a coffee, and likely more than an average day at the office. Is that lying?
People also dress up for dates. They wear makeup and nice shoes. They’re not liars; they’re dating.
And all of that makes an impression before anyone has said a word.
