I (21/M) just came to the realization my (19/F) girlfriend is a moron

When we first got together I thought she as the sweetest, kindest, and most adorable girl I've ever met. I thought, "this girl may actually be different, she may be the one."

She has her own issues in regards to anger and such but I always disregarded it as us not communicating well. If things got to overboard and I just decide to not bother with her, she would apologize and things would get back to normal. She would find the smallest things to get upset about and accuse me of wanting to leave her.

We've been together for a year.. and I've learned so much about her... and her ways of thinking.

I'm in no way the smartest guy in the world, though I may have my issues... I have common sense.

I decided to travel out of state to finish my degree and left my gf to stay with her parents. I get allot of calls about what arrangements she's gotten into and what angered her that day. To be honest, I don't know how she ever lived with them before we met. She doesn't really know what to with her life so I've been trying my best to navigate her towards something good. I tried teaching her and introduced her to things I love such programming, I tried motivating her to apply for college, I tried creating a resume for her so that she earns money on her own instead of getting it all from her parents. In the end nothing worked, she doesn't really want to do anything besides getting married to me.

Most of the time she gets depressed and I try my best to get her out of it and to work toward something positive.

You know... this maybe bad to say but I think for her maybe its best she just became a house wife. She doesn't seem to have much motivation besides getting married to me. Don't get me wrong, I believe in strong women and tried my best to build her up to that and well... all she wants out of life is to guarantee we get married and have little "babies". She has shown by her actions of that and nothing else.

Remember when I mentioned she has issues controlling her anger and that I left her staying with her parents? Well.. she has ALLOT of arguments with them and whenever I get out of class and call her all we talk about is what arguments she got on.

From what I know about about her, she gets angry mainly when there is simple misunderstandings. From my perspective, I've noticed she gets confused allot and misunderstands ALLOT... to the point I thought maybe she has some mental retardation she just never told me about.

I understand couples get into arguments and they misunderstand each other, I get that, but how in the world do you get into arguments not only with me but her parents ALL the time.

After a full year and reexamining our whole relationship... I've come to the realization there is something wrong with her and its not just because shes "kind, adorable, and sweet". She just maybe a complete idiot.

A week ago in our very often and common "what happened today with you" phone call, I made the mistake of telling her to think for herself. To think of new ways to solve her own problems without waiting for me to tell her. I told her that she was brilliant, smart, and I believed in her thinking capabilities. I told her she would be the best person to solve whatever problem she gets into. I thought this worked as she seemed happy by the end of the call.

Couple days of not hearing from her... I get a call from her telling me of her fantastic new solution to all her problems... she ran away from home.

To say the least I lost my shit. In telling her to think for herself she decided the best idea was to run away and... well she didn't think past that and told me how awesome it is to be homeless now and the new shelter she found. I honestly cant comprehend her. I don't get it.

After telling her how shitty her idea was and to go back home.. she misunderstood my anger at her horrible idea and got mad at me. I'm half way across the country and she thinks this is the best idea to solving her problems?? I hope you understand my anger and shock at what just happened. Who in the world wants their girlfriend be homeless when your halfway across the country.

In the end of the argument she decided I was the bad guy and ended the call. For her safety and the fact I know she cannot understand, I gave in and just begged her to go back. To just call her parents and have them pick her up. To say the least she "says" she called them but I need to be sure.

I honestly don't know what to do with her. I think she is an idiot.. there's gotta be some brain cells not there. I don't get it.

I feel if I wasn't there she would get herself hurt. I live alone, I work full-time, I go to class, I'm building and saving my money and I was even making plans to marry her.

I just don't know anymore.. I really believe she doesn't have enough brain cells to think let alone do anything without me. I don't want to think for her, I want her to think for herself and this is the shit she gets herself in when she thinks for herself.

I feel I have to be with her to I dont know... be her common sense. I don't know what to think, am I the only one having to deal with something like this???
