- Big deal
- Not a big deal
Most Helpful Girl
You lied, therefore you don't respect her, or your relationship with her, enough to be honest. There is already deception in your relationship and so it's not an authentic one, and she isn't really trusting you, because you aren't being truthful. If you progress with the lie, your relationship won't be a decent one.
Most Helpful Guy
It will come out either way. Do yourself and her a favour and say it yourself instead of her finding it out the hard way.
