I'm in a relationship for 5 years. My partner has a son. At first we are ok, until suddenly his kid change towards me. Maybe because of its biological mother. I also think this kid has an ADHD because of his physical performance at school. I recently knew my partner thought about it also since the kid's behaviour during nursery or earlier stage. Anyway, because of his change of mood towards me, I start to kinda neglect him. Now the kid is in 5th grade and one time, he grab his aunt's hair and ask grandmom to hand him knife to stab her aunt. It's kinda creepy anyway. I don't want any responsibility with this kid, for 5 years, I badly love his dad alone.
