Okay I have a question....

Okay look my sis is 16 and 11 weeks pregnant her boyfreind and my dad literally hate each othe.... they do nothing but fight each other... It isnt good for the baby is it.... so what should they do.... how can they finally get along

Hopefully when the baby arrives, they will be able to put their differences aside and act like adults around him/her. If they both love the baby [which I'm sure they will] They will be civil with each other around the baby for his/her sake ;]

we just fond out the baby is a boy yeah but I doubt they will be freinds.... life is horrible

i think your father should make that extra 10 percent first, he is the father and has a daughter in need.
something needs to be done, quick.

okay time to up date yall she was living with my aunt sharon without my dad knowing she moved into her boyfreinds house he is really mad I hate my dad sometimes to butttt I hate even more is seeing him so upset all he wants to do is sleep............... I have had a bad life already she made it a million times worse and she did it all on purpose. gosh I hate her..ugggggghhhhhhhhhhh

Um, she's sixteen and pregant, your father must be going ballistic. Give him a break and try to see this from his point of view. His baby girl is going to lose out on a lot of adventures and probably college (though not always) because of this.

Your father is not going to stop hating this boy ever... or at least not until he has a steady job, bought a house and provides for them. It's what fathers do, because they want the best for their children and that would involve a chance at getting out into the world and experiencing it properly before settling down and raising a family.

Well perhaps its time they both sorted out their differences and grew up as its not about either of them any more but about the potential of the child growing inside your sister...
Understandably your father is upset, shes so young and he has to blame someone, Im sure once the baby is born they will be able to see past their own insecurities and create a stable and happy environment for the baby...
