Bad All Over

I've been at my boyfriend's house all weekend and no matter what I do I feel like I am always shot down by his father, spoken rudely to by his little sister or having to witness a horrible family. This family doesn't know how to treat one another and it just makes me feel heartbroken all over the place. His dad has a cacophony of swear words that are always planted in the beginning, middle and end of every sentence he utters. His sister doesn't give a rat's ass about anything but herself and complains about every little detail that she dislikes or doesn't understand. She doesn't have any sense of respect for anyone and always talks with an attitude no matter what the situation or moment in time.  God I hate being here way way WAY more than I like it. I don't even know why I bother the hour and a half drive sometimes if I have to deal with listening and witnessing such a horrible family.. It drives me to tears.. just like right now, All I was trying to do was help construct a marinade for a pork loin dinner and everything I suggested was shot down by my boyfriend's father with, "don't have it", no matter what I said.. "don't have it", and last night even.. He threw a fit about having to help with dinner, "I'm so f*cking tired of this sh!t", when he had to only watch the hamburger patties grill! Big freaking deal!! You have to make sure they're not over cooked. Be happy you have meat to grill in the first place, dude. I know you're not well off to begin with but still.. have a little sense of decency at least.. and his sister. There's always a nasty mess of dishes covering the entire dining room table because no one washes what they use after they're done with it and so it was put all on my boyfriend's sister because she doesn't do anything to help in the first place and I asked if she was going to do it last night and she said point blank, "nope", and so I said that we wouldn't be able to eat dinner on the table if she didn't clean it up. The response was snooty and stuck up: "Well then I guess we won't be eating on the table then, will we?" I wanted to slap her across the face for that. Add on top this morning's little fiasco... she is so incredibly rude it's been taking all of my will power not to shove her down into a chair and chew her out for all the crap she pulls every other minute of every day. I don't want to be here anymore. I wish that this family would learn how to be nice. I mean, come on! They even treat their dogs like crap! Sandy, the basset hound is an annoying animal who doesn't shut up and pee's all over the floor if she doesn't get what she wants, and Jake, he's in the way quite often and doesn't listen.. my boyfriend's parents make it worse by yelling at them to move or to STFU and that just makes the dogs act even worse. Then after treating the animals like they're not worth anything at all, his parents snuggle them and tell them how cute and wonderful they are. Bi-polar much?! I just want this weekend to be over with.. I want to go home and not have to deal with anything that goes on under this roof here in the crap town of Finely... I can't even tell anyone how absolutely lucky I am to have the family I was born into. Respectful and loving parents who love to cook and spend time with their kids, they hardly swear even under the worst situations and always make sure everyone is treated well, even the animals. It's going to be a very long time before I come back here. I am always driven to tears and annoyed beyond belief when I go to my boyfriend's house... I hate being here so much. I am always trapped in his room trying to ignore the screaming, yelling, barking with whatever I have brought with me.. I know there are issues in this household, there are issues in my own, but a family should be happy.. Not hell.
