Never try to impress a good woman with who you're not; she will expect you to [always] be that person, after all, that is who you made her believe you were.
If you really like her, and she's right for you, let her fall for the real you, not the man you want her to think you are.
For a woman, one of the worst feelings is meeting a man she truly likes, only to meet the REAL HIM later in the relationship.
A good woman is really hard to find these days; and as men, you know a good one from a bad one. Don't be him! Don't be the man who let's the good one get away because of lies.
LET ME TELL YOU A SECRET
We are all a complete wreck—no one will tell you this; some people simply know how to crash and burn beautifully.
Another words, she's nervous too, she just knows how to play it off better.
But if she gives you the real her, do yourself a favor and give her the real you; because if you tell the truth in the beginning, you won't have to explain yourself in the end.
