A great friend will tell you the truth, even when it hurts. She'll share your beliefs and point you toward God (instead of pull you away from Him), keep your secrets to herself, encourage you, and be someone you can respect. Not only should we look for girlfriends who possess these qualities, but we should work to be that kind of friend, too. On the flip side, treat girls who are mean, competitive, liars, superficial or gossips like the cafeteria’s green bean soufflé: Avoid at all costs!

As for getting past the "mask" you mentioned, I think that usually comes with time. Some people are comfortable just opening up right away, but others feel insecure (thus, they put on a fake mask) and take more time to get to know because of it. That's part of the joy (and sometimes pain) of making lasting friendships.

Love,
