So just a little background, I am not the type of person who was raised to keep my mouth shut when I have something on my mind. Both my mother father and brother, we all tell each other like it is, especially when we're being an asshole or disrespectful. I'm 26, my fiancé is 27 and my fiances brother is 30 years old. We are currently living in my fiances parents house (just me, my fiancé and his brother.) his brother is a complete fucking mooch. He doesn't contribute to the house AT ALL. He is a complete slob. Just a few examples, his room literally wreaks of trash because he keeps dirty dishes piling up, molding food & plates, dirty laundry piled everywhere. He doesn't clean anywhere else in the house, we (my fiancé or I) will scrub the kitchen floors, bathrooms, clean up every inch of the house and he doesn't respect it. He'll shave and literally leave all of his hair all over the bathroom sink. We buy food and he doesn't contribute to the groceries but he'll sneak food and eat our stuff without even asking. He has a shitty car that has some problem and bad tired that leak air, so my fiancé has been letting him use his old Honda he was supposed to sell a year ago, FOR FREE. Yet we've been wanting to sell it soon seeing that were having fun our first baby in October. My fiancé & I were avid smokers before we got pregnant, in the past he has snuck into our room and stole weed from us. So here's the problem, my fiances family is UNBELIEVABLE different than ours. They won't say shit to each other. His parents never even spoke up & parented when they needed to. So my fiancé is the same way and never speaks up. We decided to start wearing no shoes in the house after scrubbing all the floors down because shit always gets tracked in, he did it for about two days and then stopped. I never say anything because I'm trying to keep the peace, I try to let my fiancé "handle it." But he won't say anything! His parents have been gone for 4 months in Florida because they're about to retire but they come home to tomorrow. My fiancé has told his dad everything and apparently they're going to "handle it." Were buying the house off of them once they leave for good in the fall but there's no fucking way I'll be living in this house with myself, my fiancé, our baby and his mooch ass brother! Idk how much longer I can keep my mouth shut. Oh & these pictures are actually of his mothers room (he's been staying in it since they've been in Florida) & the one thing she said to him before she left, "please please please keep my room clean, don't let it get horribly messy like you let yours get." This is actually a picture i took two months ago, it's way worse now and he hasn't cleaned it once. Doesn't even respect his mother.
