<human>: I've now been dating this girl who for the past 4 months of dating and 6 months of knowing one another has been great however recently whenever we go out she will get upset over trivial things.

Such as a friend of mine cracking a joke at her or one of her friends doing something meaningless to her such as ditching her on a night out due to a serious illness (turned out to be life threatening).

The other night was my birthday do and she ended up crying because she was visibly grumpy at something and when I asked her what was up she cried stated she had 'ruined my birthday', I felt upset but didnt chase her and let her mellow out on her own. 

What I dont understand is that afterwards she says to me to let her know if she ever starts getting erratic and over emotional/dramatic so that she can go somewhere and calm down and then come back with a straight head on. But I'm nto sure if this is the correct way to deal with it, a friend of mine said this to her once when she was upset at me for a trivial reason (I didn't witness some guy slap her ass whilst she was at the bar and she simply wanted me there not to fight him but for her to hug me and such to let him know to back off.) Anyway he told her she was being dramatic and to 'be quiet because you're on your way to an oscar' and she ended up storming off, ''breaking up with me'' and now doesnt even acknowledge that the guy who said it exists.

Give me a shortened version of the text
<bot>: So my question is... Do I tell her when she is being a drama queen or would that simply make things worse?
