Ya ever heard the age old saying of people speaking the truth when they are drunk OR having more guts to do things when they are drunk or saying something they feel is very important to them but they are too embarrassed to say it thus they use the cover of "being drunk" to say it.
Well that is exactly what this girl is telling you, you need to stop over thinking this and just enjoy being on this side of the fence for once.
And next time she offers the whole "I'd do you anywhere" type of text keep it till she's sober and you're with her and flick it up and say "so when are you gonna come and prove this to me?". Doing this in person has a bigger impact on her then if said over texting.
