Being a Wife

So Im 19. Im married and my sister in law is prego. Im super happy with my husband and i love being a housewife. i clean and cook and keep my husband happy but inside im so fucking mad. my sister in law is prego and im pissed they have only been together for 6 months so i dont think she should be prego and im so sick of hearing about it. i love her and im happy for her but gosh shut the f up. And my mother in law called me a slut and bought me new clothes cuz she hated what i was wearing like f off your not my husband. but all of a sudden cory hates that i show off my boobs or that other girls do. he never cared before. living with my young sister in law is hell she is a bitch and she thinks she is the best she is so fing annoying like f off i clean up after you show some respect. my husband says i should stop cleaning up after everyone but i have to clean or his mom is going to want us to pay rent like i fing moved in with them so we didnt have to pay rent but of course i need to clean this big house all by myself cuz im the wife. i love being a wife im just not big on the in laws
