As for contacting her CRW, start taking things slow, the new girl already has. Sandi always said that girls like a guy that plays hard to get, not one that wants to get married on the first date. Now i've been known to quote Sandi incorrectly before, but thats the gist that i got.
But be yourself, you have your life ahead of you.
Just cos things are going right, doesn't mean that they were always wrong.
