Old drama coming back up (mother in law)

Ok so if you read my other post you know that my mother in law is mad at me right now. Really thought this was over the pizza incident but apparently according to the sister in law who likes me this actually goes back two years. Also please note for the last two years Iv seen this woman almost everyday, have talked to her, hung out with her, driven her places, bought her things, spent every holiday with her. I thought we were pretty close. But apparently she’s hated me every since the day I said I didn’t like her in my house.

Now let me take his story back to when my son was 3ish months old. He’s now almost 30 months old. My mother in law would come over unannounced when ever she felt like it, no heads up what so ever. It was a super sweet gesture, she just wanted to see the baby. She usually brought over some dinner. BUT there was a lot of times she’d walk in with food and I’d be in the middle of eating and then I’d feel bad, or as my son got older she’d be trying to feed him something she took time out of her day to make him but me not knowing she was coming just gave him a bottle 10 minutes ago. And now I’m standing there all uncomfortable like just eat the food. Or she’d walk in and I’d be in my underwear or in the shower. She never knocked either and I never wanted to lock the door and make it awkward. Also plenty of times she took time out of her day to drive to my house to see the baby and bring us food and when she’d get there we would be sleeping.

Also when my son was born I had lived with boyfriend for a total of 9 months. I knew him for a total of 10 months. We had a very fast moving relationship. My Spanish was horrible back then, still isn’t the best but I can at least have a conversation now. So I couldn’t even talk to my boyfriends mom at the time other than a few words, she’s just walking in my house I’m in my underwear trying to breast feed my new baby and she’s trying to get me to eat before the food gets cold but I just made dinner. I eventually just had told my boyfriend it had to stop. I didn’t care if she wanted to come over, I didn’t care if she wanted to eat dinner together every night. I had no problem spending time with her, and I loved that she was taking an interest in my son. But I need a heads up. A phone call, a text, anything she lives two blocks away just call and say your gonna be here in 2 minutes so I can put on a shirt of not put the baby down for a nap or something. I guess she took that as I hated having her around.

Do y’all think it was rude of me to say she couldn’t come over anymore with out giving me a heads up first? What would you guys have done differently? Any advice here really I’m so confused how this even still a thing

Thanks in advance for the comments guys
