Depends on if you're the healer type. My gf used to think she was ugly and worthless but after the last year and a half she's become happier and happier with herself and with me.
For all-purpose red flags, try these:
>doesn't care about your interests (not that dhe has to like them, but that she doesn't put up with them, i.e. "stop playing your stupid games" "why do you like that nerdy stuff anyway" etc)
>ultimatums/her way or the highway
>tattoos (exceptions happen, but it's normally a sign of a thot. Especially cross tattoos. Those are thots that think they're pure.)
>drinking/smoking/etc (this means she doesn't care about appearances, health, or tradition. Exceptions obviously exist, but be careful)
>politically active without actual understanding (these are your Berkeley types, and they probably would have called you a misogynist already, but just fyi. It also falls the other way in theory but I've never met one personally.)
>attention seeking behavior (gamurr gurl, not like the other girls, etc - never loyal, you're never enough for them)
>emotionally unhealthy (if you're ever afraid of saying something to her that you wouldn't be afraid to say to someone else except for certain circumstances, then she's not mentally fit yet. Avoid.)
I'm probably missing some that would help but those were what I thought of right now. Obviously exceptions to ALL of the above exist, but keep these in mind and judge for yourself.
