We moved in with my dad when I was 5 months pregnant... the first week was ok but after a while it got crazy... they made us pay rent which wasn’t bad at first since it was only $75 every two weeks but then my step mother decided to quit her job and raised it to $240 every month... it wouldn’t have been so bad if my half sister was stealing from me or messing with our stuff... at first it was just my deodorant, then she blocked my husband in MY phone so he couldn’t reach me because she was mad I wouldn’t let her use my hotspot....but then it got worse... she would lie on us to my dad and he would believe it...walk around the house with an attitude and say she wishes we would just leave... she stole my perfume that I got last year for Christmas... put salt in my husbands soda while we were out... put syrup in my sons nose suction bulb, stole my toothpaste, stole my gum... and last night she lied on me when I asked her to open the door saying that she was in the back of the house when I clearly saw her staring at me through the blinds and then I found out that she poured water in my clothes bag while I was out, soaking half on what I own.... now people keep asking me “oh did you let your dad know?” so I tell them nope... what’s the point... my step mother always Butts in and gets mad at me when I tell her my stuff is missing... it’s like she tries to blame us for our stuff missing like we’re sabotaging our own stuff just to blame it on the kids... I just got my section 8 voucher on Tuesday and I have until March 19 to find a place but not everyone takes it:...I don’t care about myself , I just don’t want my son around this mess
