Search Results: what is girlfriend material

Im not looking for a hookup, im just looking for a girl to have a long term monogamous relation,
Im a fairly rich and good looking guy,
These were her qualities -

* She used to show everyone in class through her wallpaper of mobile phone that she is engaged with a dude, and also she was maybe in a live-in relation with a guy.

* She saw me, and then she started flirting with me, although i was not sure because of all the rumours, and then one day i was talking on phone with my friend, she thought i was talking to another girl , and then she started to flirt like a slut, with every guy of the class. (mostly with my friends)

Was this girl a good girlfriend material? Or I dodged a bullet?

I did not pursue a super - hot girl because of her past.

My friends saw her hugging a dude, coming in car with some dude to college and then some dude picking her up in car from college.

So i knew that she was involved with someone, so i did not pursue her because she is not good long-term girlfriend material, she is a cheater and is only good for friends with benefits type of relation.

This girl made her sister and friends stalk me , she was kind of obsessed with me.

Now, here is the problem, mostly all girls have ex boyfriends but my problem is if a woman is with a guy and she is already lining up a replacement that means she is weak to go single all by herself,
if a woman constantly needs one guy after the other, isn't it a sign of weakness?
