More specifically:

'who's that girl youre texting/talking to'

'you just want me for my body/sex'

'this guy was flirting with me/being creepy towards me blah blah blah'

'i miss you/do you miss me' (more a comfort thing, I know, but I still have no clue how to respond sometimes)

attention seeking behaviour/clothes + 'look how hot I am/I'm so hot' (don't know how to deal with this one at all)

Cheers.
