Damn people . . . I just want to say:
Fall in love much?
I am not quite as nit picky as most of you . . . but I guess in the spirirt of what is posted I can write down some of the qualities that might be the difference between Ms. Right and Ms. Right now. This is something quite a few guys and some gals I know agree on.
Remember: This applies more to the forever idea.
Deal Breakers:
1. Struggles with her weight.
If she is struggling now what is she going to look in 10 years or after children?
2. Has any problems with physical intimacy and sex (in terms of comfortable with her body and you).
If during infatuation, when you feel the closest, she has these problems they are just going to get worse and you are going to be her husband not her therapist 
This covers body image problems as well as being uptight about sex.
3. Has a good relationship with her mom . .
and her mom is a real "piece of work" 
Old male axiom: Look at the mom, there is your future wife.
4. Likes bad drama. . .
we all know the type . . . life is adversarial enough without going home to it.
5. Treats her pets better than people . . . [i]she will take better care of them than you, and lets face it you can never be as unconditionally devoted as her pets. [/]
6. IS not very attuned with her emotions and not very articulate ina good way.
It means her lack of ability to speak well and express herself meaningfully will hurt you almost every day you spend with her!
7. This goes with number 6: Dramatically angry.
Do you like things thrown at you?
8. Also goes with number 6: Passive Agressive
Hello, days of uncomfortable attitude filled with constant "Fine" and "whatever's" with you trapped in marriage.
These were the ones a bunch of my male friends and some of my female friends agreed on.
A lot of the ones you people named seemed pretty trivial and destined to leave you unhappy.
