My girlfriend is constantly asking me for small favors, but she demands it very rudely. And when I complete the task, she doesn't even say thank you. I've tried to talk to her about this multiple times but all she ever says is "you whine too much","quit being a baby" and things like that. It gets me to the point where I just want to rip her head off. Not literally though, id never hurt her.

You should try saying no to her 'requests'. Then maybe she'd ask nicer and appreciate it more when you did do stuff for her. Stand up for yourself.

It sounds like she's just usiing you. Just think, if this bothers you now, how bad will it bother you a few months (or years) from now. Unless she's perfect in other ways, it's time to cut bait.

Instead of wanting to rip her head off, why don't you want to break up?

Why be in such a suffocating relationship? You're just torturing yourself.

Oops. I'm guilty of sometimes doing that to my own boyfriend. Only, I think unlike her, when he calls me on it I realize it and try to stop. I don't think I'm rude with my demands, but I'm used to being in charge. Of pretty much everything. So I know how to give orders to get things done. And sometimes when I'm with him I can't get out of the authority mode I'm used to. Usually him getting upset and refusing to do something snaps me back though. If she's worth staying with, try saying no. or make a deal. OK, I'll do this, but you have to do that for me. I usually realize that I'd rather just do the thing I'm asking my boyfriend for myself, instead of whatever he wants me to do in return.
And if you want a thanks, you could make it a point to say "yes, you're very welcome..." and wait for her to reply with "thank you" she may need some reminding.

You should just tell her no or tell her if she is not going to be thankful for it and call you a baby for complaining that she is not thankful for what you have done for her then you won't do it. Period.

I know girls like this. With them it is 'my way or else!'
Tell her back that she sounds like the baby always demanding. Seriously you should really reconsider being her boyfriend cause it will only get worse. She sees no wrong that she does, she doesn't see the way she is and she will not change for the better.

I am like justcurious too. I am use to telling people that do work for me what needs done and how I want it done. I have a strong feeling she is just the self centered type though.

Do what my husband does stare at me till I feel stupid and then I realize I was rude lol

Stop listening to her and tell her if she wants something done she can do it herself.

People who need control go nuts when you ignore them.

I would really reconsider having sex with her if this is how you feel.

This is when I tell the girl to kiss my a$$ and show her the door... don't put up with this treatment. It only gets worse. NEVER let yourself be treated this way... EVER! Ain't no woman worth that garbage.

Learn to say no to her, and sex, because if she gets pregnant, (the only 100% birth control is abstinence, everything else out there can fail) you will really be catching it. 15 is to young to be trained to be a wuss, and a baby daddy.

OMG I just realized because of Zoe this is a 15 year old... damn she is not your mom do not put up with that
