At first she was acting as though I was cheating on her overtime she came to the fact guys can have friends who are girls to.

run away fast from those girls. jealousy is the worst, not just in China

Absolutely correct, but on the other hand, the Chinese girls are never after just one thing so even if it seems like it's not a big deal when a boy is talking to another girl who is not their girlfriend. Those girls are after something and the girlfriends know this.

I can only relate my personal experience with my GF.  She has her group of friends, and I have mine.  She knows my friends and I know hers.  There is no "hitting" within members of either group, so I am cool with her talking to her friends, and she is cool with me talking to mine.

BUT, if I happen to see a former GF, all bets are off.  Even if I just reply to "Hello" with a "HI, HOW ARE YOU?", sparks will fly from her to me almost instantly.

Its funny , almost any woman with a brain would not put up with a jealous BF. But my experience is that it's not a two way street. Almost any GF I've had gets jealous. Maybe I can't blame them, I can be a little forward and people in general like talking to me, I'm ''entertaining''. So if I get going on about something, I think the GF feels neglected because I'm having fun with someone else. I dunno-maybe.
 I try not carry on too much. I only look at other women sideways because I have a trained reflex from getting smacked.

I have to agree with Happy...just chatting with other girls is normally fine.  But if I even respond to a former gf online (QQ or Skype) she goes ballistic.  I have had dinner with an ex secretly before and after was terrified she would ask questions about where I was, as I am a bad liar.
I love how I can selectivley delete sms messages on my phone.

But the WORST is when she asks me if I think her girlfriend is beautiful.....how the hell do I answer that without getting killed??

When in the early stages (dating, or pre-dating), I chat with said girl, and I mention that I'm still good friends with my ex, and that I often chat with her online... If they have a problem with this, tough $#!+ !!!!

I also mention, for quite a few years of my life (including now, to some extent), most of my friends are girls.

They're allowed to be jealous - but they aren't allowed to go batshit on me!!!

Yep, as everyone said, any mention of the ex, and she goes overboard (unless we were on a boat, then I would probably go overboard).

Here is different. Back home if you cheat on a girl, you will lose her trust, but here, you never start out with her trust. they always have a suspision that you will be unfaithful. And it takes a long time for them to give you that trust.

For other girls. its different for every case, but as long as she doesnt feel excluded then its no problem

My wife used to fume. I remember one night a good friend of mine from France came out. When she saw me she kissed me twice on the cheek. Sure enough, lying in bed that night...... "Who was that girl who kissed you?" and the ensuing convo. 

Sometimes, but she's not bad for it. Back in Canada I dated girls who were ten times as jealous and paranoid. Of course, I think that's an age thing, too. I've gotten less jealous and suspicious over the years myself.

i dont have this problem . i tell them at the very begining that jealousy leads to break up. the jealous bf/gf routine is more about control than lack of trust. either way if you dont trust me find someone else that you can trust

You are right Ammia they do tend to think that just about all other women are a thrett to their relationship
mine included (understatement)
The only girls that dont make her go into terminator mode are either not very attractive in her opinion or somebody that I concider to be a family member wich if I was from Tasmania could pose a problem.
It can be a little frustrating that not only she has little trust other girls but she has little trust in me.

China's social structure is a little strict at times. Depends on where she was raised?
