So we have been living together in peace for the entire year 2020 with SS 13 and with his mother still out of the country since 2019 October. 

Beginning of January MIL wasn't feeling well, she had a chest infection so DH asked her to come visit us for the whole month of January,

I picked her up from the bus station on the 4th of January, a week later my DH and DH's distant relative who is twenty years old left for church choir practice. (Name is Hope, she has been living with us since March and helping me with house chores and we pay her) 

I took my bio son who is now 3 years old and went to visit my mother's sister who lives 6 streets away from me. 

I left MIL and ss13 home alone so they can freely gossip, i left my toddler's phone recording and hid it in the living room (he uses it for educational games and nursery rhymes)

I was gone for four hours, when i came back I took the phone and listened to the recording, I have been telling DH frm day one that his son is a liar and whenever his grandma is around he tells her everything that happens in our home including made up stories to make me seem bad. He never believed me. After living with SS13 in peace for over a year I really thought he had changed but I needed proof.

I was appalled and I felt sick and lost my appetite when I listened to the recording, he told his grandmother everything that happens in my home, including the arguments I had with his father. He told her that our marriage will not last, it will end one day. He said he is being illtreated, I make him clean the house after school and do all house chores while I sit and do nothing, he said I give snacks only to my bio son as for him he doesn't eat cereals or biscuits because I forbid him to. He told so many lies just to make me out to be a bad step mom. 

I've been nothing but kind to this ungrateful child, i have been a mother to him making sure all of his needs are met, I have been helping him with his school work, I have been grooming him, every skill he knows I'm the one who taught him, I've taught him how to cook, clean up after himself and proper manners. 

My family has also been so kind and welcoming to him, I go with him to my mother's house, her work place and my aunt's place  but he talked bad about them to his grandma and said they are evil people who don't want him in their homes. He said my whole family is bad and satanic. 

He even talked bad about Hope, saying he doesnt want her here, she thinks she is beautiful and she is dumb and so on.

MIL also told SS13 bad things about her first daughter in law with whom she has been living with for the past 3 years, she told ss13 all about their marital issues and everything that goes on in their home.

I was really appalled, how can a grown woman gossip with a 13 year old, speaking bad of the daughter in law she is living with and speaking of her marital issues. 

A lot of things were said. I confronted them about it, and they denied everything and I told them its no use because I have a recording.  I sent the recording to DH and he was shocked and really disturbed.  But then he made excuses for them, he is just a kid,  he was over excited to see his grandma,  the old lady is just lonely so she was sayin things she don't mean. They were just talking bla bla bla.

Well he did talk to them about it and ordered them to apologize to me but things will never be the same again. I will never trust SS or MIL and I won't  bother spending a penny on them.

I hate stepkids who are evil and ungrateful,  he is the reason my MIL hates me becz he has been feeding her lies about me ever since day 1.

I was really hurt  by SS, I do not understand why he would speak so ill of me and tell so many lies about me just to paint me black. At 13 years old he is not a baby, he knew what he was doing and what he hoped to achieve by telling lies.

I feel scared of him, he is a wolf in sheep's clothing, all this time he has pretending to be a changed person, it's all an act. I don't think I will be able to forgive him for this. He doesn't appreciate me he has no gratitude. It is not easy loving and accepting a step child and I thought he would be grateful he doesnt have an evil step mother like cinderella did. 

He even dared to speak ill of my mother!! That's unforgivable.  I never talk about SS's step mother and what a whore she was , sleeping around with her sister husband's and her husband's best friend and the whole town, but he doesn't talk bad about his slut of a mother who didnt want to take any sort of responsibility of him. She has never been a mother to him but just a surrogate. But I the step mom just because I'm not his blood he will never hesitate to stab me on the back and throw me under the bus.

No wonder people hate step kids, they are a waste of time, affection and every cent you spend on them. There is no reward at all! From now on I will focus only on my bio child whom I know will always be loyal to me and appreciative of my efforts.
