I've been with my fiance for 5 years. He has 2 kids which he has full custody of since the mother abandoned them almost 10 years ago. One boy age 12 next month and one daughter age 9.. she'll be 10 in Oct. I don't live with them at the moment..and to be honest i don't know if i want to again. Both kids wet the bed every single night! Then they sit in it all day since there are no bed sheets on their bed, the urine soaks into the matress. What baffles me is they don't find anything wrong with the bed wetting..and neither does their father. He says they'll grow out of it. I stay with them on weekends and the smell coming from their room is horrendous! Living space is very small for time being. It smells of an adult soiled diaper. Both kids also don't use toilet paper. SD was walking around with a poop stain all day last time i was there. She's too busy bossing her brother around and breaking everything in sight to care about poop on her. SS also doesn't wipe, going through puberty, and smells horrible if he doesn't shower daily. I can't stand to be next to him when he smells of BO. My fiancee doesn't seem to have any problem with any of this and he gets upset with me when i tell him i cannot stand the smell. He had his daughter sleep in his bed the day before I came and she peed on the sheets, blankets, and the pillows stunk! I cannot live in that filth. I have to get drunk while there to be able to sleep. SD is in 3rd grade and cannot speak correctly.. it's extremely hard to understand her. She also can't spell. She failed 2nd grade but was still let go to 3rd grade. She's currently failing 3rd grade as well. I never ever see either child do homework. They both rip apart all their toys..12 year old still plays with stuffed animals and dog toys! He's about 60 lbs overweight and his father tells him it's all muscle. It's definitely not! My fiance is constantly defending all their bad behavior and making everything everyone else's fault. His daughter failed 2nd grade and it's her teachers fault according to him. I've asked the kids to please not walk all over SO bed which i sleep in as well. They walk on the floor then track it all over the bed.. it's sickening. But fiance wants ME to sit a specific way on the bed to prevent the kids from walking all over it. Why can't he just ask them to not put their dirty feet on the pillows?? His daughter thinks it's cute to steal.. because she told me this. They live with their grandfather and she steals money from him often. Last week she took $200.. it's eventually found and given back. SO buys them everything and all they do is break everything they have. Both kids got their 4th tablet for Christmas..guess how long the tablets lasted..1 month!! Now they are asking for Iphones! Finance spends all this money on them when they aren't even doing the right thing. It upsets me more because my current ring was only $25..yet he wastes on new electronics which are destroyed in days. I don't understand and I'm at the end of my rope. I hate going there.. I can't stand how filthy and irresponsible his kids are. Whenever i talk to my fiance about his kids, he'll get upset and turn the argument into something wrong i did in the past. SD has also killed all our house pets..birds, ferret, bunny. I don't know what's wrong with them. They aren't babies anymore but they won't grow up! The kids are ruining my relationship because all they do is cause problems. I try to help but the kids don't want to be bothered with anything but games games games! My 4 year old nephew is more mature than those 2 combined. Please help..i need advice on what i can do. I love my fiance​ but his kids make me miserable and cause us to argue.
