So I have a friend that I’ve know since preschool. We went to primary and secondary school together too so there is a strong connection there. I enjoy her company and we always have a great time together but since having kids and getting married I'm starting to resent the fact that she always assumes I will pick her up and drop her home because she doesn’t drive and now I live further away (1 hour round trip) from her but she has never once offered to pay fuel money ! I always book and plan where we go as she leaves it up to me with having the kids to think about. The other day she forgot to pay me the cash for the tickets we got so she bank transferred the ticket money across but just rounded it down and it didn’t even cover the ticket money plus I packed a lunch for us all. She’s great with the kids and always helps me out when we take them out together which is super helpful but I can’t help but feel used sometimes and that she just feels entitled to lifts and doesn’t take into account I’m going out of my way to collect and drop her home plus the cost of fuel to do this. AIBU to bring this up and potentially lose out on a lifelong friendship or make things permanently awkward and never the same again ? Also will take suggestions of how to approach this sensitively !
