Another diactritic-less SMS has me stumped :(

[Furty]

Having problems with this one:

Anh dang lam gi vay em nho anh lam.

Hrmm, there's just too many choices for this Vietnamese novice

Anh dang/dâng làm/lắm/lầm gì vay/vầy/vậy em nhớ anh lắm ???

Please help! TIA!

P.S. I'm not actually posting every SMS I receive by the way - I'm now getting through at least half of them myself! With your help that statistic will gradually improve!
