Making relationship with girl that has mostly broken up with old boyfriend but hasn't quite

A pretty common circumstance that I've observed multiple times now is that a girl who you meet as a new possible relationship is exiting out of an old one. This makes sense because an attractive girl will be in a relationship most of the time and only exit during "refractory" periods between different mates. You will probably meet her and start dating during this refractory period or right after it. (The early part of the refractory period is what people call "on the rebound.")

She still has a connection to the old boyfriend, and it's mixture of old love and often dislike also (whatever made her not want to be in a relationship with him).

Here's advise for cementing a relationship with a girl in this period which may last a few months or so. Keep in mind that she will often act as if the period is a permanent state even though it is not. (While she's upset with the breakup, she'll make statements like she's rather be a lesbian, etc.)

(1) Expect that she will be somewhat mad at men in general at first. Some of that anger can get displaced to you. But, for the most part, if she's a decent person, she's still going to be nice most of the time. (Women have unpredictable waves of emotion in general.)

(2) In all cases dealing with women, you should be a "rock." You should be firm in your position that you want a relationship with her. (By the way, you don't need to be firm with her about your position on technical matters like computer stuff. In these cases conversation should be mostly for fun. The only time a women is interested in seeing you "win" a technical discussion is if it's with another man.) She will test you in various ways to check loyalty and just how easily you might change your mind. For example she might say she has a new boyfriend just to see your reaction... you choose how to respond.

(3) Key point: Being as social as possible is good, but be careful. You never know how a relationship will go long term, and the beauty of being social is that you will maintain a connection to many people, so you can select who you want. However, when in social situations, women don't want to see their new interest (you) actually persuing a relationship with other woman. So as you are being social, be careful to give her the most attention and keep interactions with other women strictly playful, not overtly sexual. Also, choose the events you go to wisely, there is no need to ever go to something like "speed dating" when you can go to other events like parties or whatever without giving off the vibe that you are actually looking for someone else. Finally, let her know what events you go to. Even if she doesn't go with you, she wants to know about what you are doing, and make sure the events you go to are reasonable (not something with dating in the title) because you don't want to give the impression that you are looking for someone better than her.
