"I do think women are genetically wired to pursue commitment more than men--we haven't lost that part of our monkey brains yet. But many women can overcome that impulse or are less interested in commitment due to their circumstances growing up."

I agree that this is true and I think multiple mates is a strong evolutionary directive in men.  Interestingly (and you've probably heard this), studies of bonobos and chimps have shown that the females, while establishing long term partnerships with a male, will have sex on the sly with males that are socially and physically "superior" but will raise the offspring with their mate.  They increase their chances for dominant offspring this way.  So the evolutionary sword cuts both ways when it comes to cheating.  Maybe that will make Ana feel a little better about  the whole thing. 

"Men seem evolutionarily drawn towards the feminine, week, and needy for some reason."

Well, naturally toward the feminine.  There are certain physical characteristics that are going to make any woman more successful at finding a mate no matter what.  There's no getting around this -  it's hard-wired into the male brain. 

I don't know about "weak" though.  That isn't it.  Can't a woman be both feminine and strong?  That idea is what really trips the trigger for me.  I would phrase it more like this:  Men seem to have an evolutionary predisposition to dominate.  I think they just tend to be more successful at this with a weaker woman and so they settle for it.
