So I will do my best to keep this first part short because I could go on and on. MIL is incredibly controlling and religious. We are using hormonal birth control and she is a believer that it causes abortions every month. She slyly asked what we were doing after the baby because I told her this was our last and like an idiot, I answered. I knew how she felt and should have just told her it was none of her business but well...I didn't. By the end of the conversation she accused me of being okay with "aborting my children every month". Of course DH got involved and they got into a huge screaming match over the phone where she told him I was lying and questioned how we are raising our children (we aren't religious) and played the victim because that's what she does. DH is still communicating occasionally with his dad, but other than that we have cut off communication with his mom and for the most part his siblings (they live with ILs).
Our 4 year old DS goes to school and has a Grandparent's Day at the end of September. My parents both live very far from us. My mom is trying to fly here to be there with him for the day but it's hard for her to get time off. I know we cut them out of our life but I can't help but feel guilty for my child. I'm considering DH or I just going but then how would I explain that to his school and what if he feels left out? Should I keep him home with me that day instead or just ask them to go with him? Should I explain to him why his grandparents aren't going if I decide not to ask them? Looking for advice on all of this honestly.
