Future MIL is nutty

Jas

I have a child from a previous relationship. My son was 18 months old when my current s/o and I started dating. My son is now 4. My s/o’s Mom (my future mil) disappeared with him to take him “on a walk” but took him to the store to get him toys. My son is autistic and prone to outbursts when out of his comfort zone. I stood up to my

Future MIL and said no. You have to ask permission. She then disappeared and refused to discuss it. Over Christmas my

Mom (a filipino immigrant) got to meet her for the first time, and my future MIL played on her phone instead of talking to my mom. Am I right for being angry?!
