AITA for stopping my parents talking their grandson to the pantomime as she stole my plans?? – I am currently having difficulties with my parents. I am a 44 year old single Mum to a son 9.

We live close to my parents and they see their grandson every 2 weeks for a few hours and I go to the gym and have a little time to myself. I appreciate their support but they are getting too much. Any time I say I am going to plan to do something with my son, they will book it and also try to get in there first. Things are expensive and when he’s doing it for the second time it’s not as interesting so it feels like a waste of money and time planning. It’s got to the point I won’t tell my parents anything. Examples of this are when a film is coming out in a few months and he’s so excited and I say I’m looking forward to taking him, or there is a new local attraction being built that we will go to.
They’ll always have him for a few hours at some point and pip me to it knowing I was planning to take him. The most recent example is the pantomime. Booked our tickets in September as they sell out, my mum asked to have a few hours with my son (her grandson) the day before we go to the panto, and I found out she has panto tickets booked!! The day before mine! I even asked if she wanted to come with us when I booked and she said she had plans. So I’ve cancelled her seeing my son. I have spoken to her about it a lot but also very recently after she bought him the present I was getting him for Christmas as a random gift and I was livid. I find it so intrusive and it’s all my effort and plans stolen! I feel awful though….but she has no respect for me or my boundaries. I have pulled back because of this behaviour before and I can’t see it changing. AITA?
