Just another vent

My SO expects me to live up to a parental role to his kids however I feel more like a maid/nanny
anywho

My SS has got into SO much trouble last month

He was using my daughters tablet to watch raunchy porn every night and thought he could google naked pictures of me (HE IS 9 years old)

He got an F in math

He had to go the principals office for running through the halls kicking each door and getting smart with his teacher

the day he was sent to the princiapals office he went shopping and got $250.00 worth of clothes and sneakers none of the behaved kids got a single thing he went out to eat with his dad he was on punishment which consisted of him watching tv, outside playing football and trick or treating and doing about 10 math problems

Im sorry thats parenting at its worst and my oldest stepdaughter is confused and feels the favortisim

Please no life advice just on the topic : )
