I need help deciding what is fair for my child/husband/stepchildren. My DH has a degenerating spine disease and has lost his job and is unable to drive due to his medication and pain. We have a four year old daughter together who has just started school and my 10 and 11 year old stepchildren who live a fifty minute drive away, they spend every other weekend with us. I work part time including Saturday until lunchtime and live a long distance from my family so have no extra help. My stepkids have a huge amount of weekend activites from now onwards, I have offered to pick up my DSD from guides at 9pm on Friday and take both children back on Sunday whether it be to my DSS's rugby training or home, their mother refuses to drop off my DSS on a Saturday after his rugby and thinks I should pick him up which means I spend my day working and in the car so my DD and DH have no transport. There are also additional activities on Saturday pms which again are 50 mins away so on weekends we have them I spend no time with my own child and she has no transport for her own activities. If I refuse, my DH and DD don't see their children/siblings, but if I do it they are stuck at home and don't see me. AIBU to think that their Mother could be a bit more helpful with the driving as they are her children? (sorry for longwinded post but it's complicated!!)
