So my mother in law has not been the best mother to my dh. His parents divorced at 15 and he moved in with his Dad. Since we got together 8 years ago I encouraged a relationship with his Mum which he now has (he's now 38). We have 4 young children and she barely does anything to help, if we ask for a babysitter she'll say yes but be home by 9pm as this suits her new boyfriend and she only agrees to this once every 3 months if we're lucky. My parents have my younger children on Mon and Tues as we both work full-time so we don't take this for granted. This weekly parents are not only having the 3 Yr old and 6 month old but also our 4 and 5 year old as its half term. The elder 2 are in holiday club Wed and Thurs and as dh had just started his new job he is unsure of finish time. I finish at half 5 and holiday club finishes at half 4. To help for the 2 days he has asked his mum (who only works until half 2) if as a back up she could collect the kids. She doesn't drive so has basically said no and I've seen a message she sent to him saying 'she should have thought about this but all she cares about is being close to her parents'. Basically blaming me. I'm furious and expect him to have my back. My choice of house is nothing to do with where my parents are but a choice of the best area. My mil lives in a rough area. Opinions more than welcome
