Family member is a shit parent (neglectful, bad choices etc) social services are involved but kids lie to cover it up to protect the parent. Other family members just shrug their shoulders and let it happen, the other parent (separated) also doesn't help much, it is only me that looks after the kids but it is becoming mentally too much, it is constant drama and it's starting to impact me. AIBU to put boundaries in and not say yes to looking after them all the time, or should I being doing it all because of the situation the kids are in.
