<human>: Can you succinctly summarize the text in 1-3 sentences?

All night I was developing a crush on this cute girl. Finally I got drunk and nihilistic enough to go talk to her. We had very brief words before she started to walk away. I said "What, will I never see you again?" She said "You want my number?"

She gave it to me, but as I'm entering it she explains to me that her ex is here at the bar -- that's why she's being all jumpy and quick -- and that they're still "very close friends." Then, just as she walks off, I realize I'm a drunk idiot and I fucked up saving her number in my phone. 

I follow her and say, "Hey, I'm sorry, could you give me that again?" She says, in a really clumsy and cute way, with her eyes obviously on the ex boyfriend (who's behind me like some lumbering monster me at this point): "Uhhh....I gotta go over here now!" 

Anyway, I finally get her number again about 10 minutes later, but this ex is like the eye of god or something. I asked her "What's he gonna do? Kill us?" She said "He might." She left with him later that night (side note: this girl is WAY out of this guy's league). 

So do I call this girl? I'm really not looking for anything but a chance to buy her a drink and get to know her, and if she wants to sleep with her ex right now that's of course her prerogative. But I'm afraid that her behavior last night might indicate she's not really ready to go on a date, yet, and I definitely don't want to get mixed up in whatever she and her towering, slovenly, creature of an ex-boyfriend might still have going on. 

What do you think?
<bot>: got a girl's number but the whole time it was happening her ex -- whom she describes as a "good friend" -- was giving us the evil eye. don't know if it's worth calling her.
