Why are women this way?

My ex boyfriend still talks to my family. My sister all of a sudden becomes a bitch when he's around. Whenever they talk about his girlfriend she mentions her name alot of times. She wants me to be jealous and be mad because he got a new girlfriend. I understand that he got a new girlfriend and I still talk to him as friends. Why do women in general like to see drama. Her husband is more laid back and doesn't do these things on purpose. My sister is just like other women always wanting to see drama. The other day his new girlfriend was here and I opened the door and said Hi to him. His new girlfriend was there but he didn't introduce her and I just didn't want to say hi out of nowhere. Anyways I told my sister I said hi to him and she said oh you said hi to her too. I explained my sister I would have but I couldn't say Hi to her plus I was also had a cold that day. My sister looked surprised as if she expected me to start saying why would I say hi to that explicit words. I don't know her and I'm not this type of way. I don't get it even my mom says things like this. Why are women this way?
