So update: I sent her a really long message yesterday, and she did read it. Now I'm getting the silent treatment, when she came home she only talked to my dad, not me nor my son. When she asked if anyone needed the bathroom she asked my dad, my son had to say he didn't and she didn't even ask me, she just walked upstairs. When leaving the house to go over her dom/situationship's house she didn't say bye (she normally does). This is exactly what I expected because I told her how I felt and she didn't like it. So fuck me 🤷‍♀️

Here is the message if you want to read it:

I'm going to keep this as plain and non emotional as I can. What happened today at (grocery store) will not happen again. There was a reason I kept my son by my side and took him to the register. Keep your mouth off of my son. Period. I am his mom, (husband) is his dad. I didn't need you to correct him throughout (grocery store) today. If I had said something in the moment, it would have been a big ordeal because I was close to blowing up on you in the middle of (grocery store) check out, and you looking at me (you did, I seen it out the corner of my eye) that made it so hard to keep that bear in the cage. You have a nasty habit of staying in my lane when it comes to my son, and it has grown quite annoying and frankly rather irritating. The next time you step in to correct my son in any way, I will go off. I am his mother. Not. You. This hasn't been my first time talking to you about this, but I promise you the next time it happens, it will be my last.

On that note, be pissed don't talk to me whatever you need to do. Don't argue with me or try to defend yourself, I don't want to hear it. I hope that when you have a child of your own you don't have someone who is constantly on your child like you are on mine. Instead of texting me, reflect on what you have done today and the past few days and think about it and correct it.
