Crazy mother in law?

Ok so I know a lot of people struggle with their mother in law disliking them. My problem is kind of the opposite. My mother in law loves me very much but she is very overbearing. She messages me every single day. She wants constant updates on my and my husbands lives. I know some families are like this, but mine is not. I talk to my mom a few times a week and update her and that’s it. Not everyday. So I guess this just isn’t normal for me. She also has opinions of things me and my husband do and always makes her opinions known. Which also annoys me because, I never asked her. And I often feel she treats me and my husband like we are children. We are 25 & 27.

Back in the fall, it was really starting to drive me crazy. So my husband did talk to her and told her to stop messaging me so much. Well she didn’t. She still messages me everyday, most of the time while I’m working. I’m currently 13 weeks pregnant and she is always asking for updates on how I’m doing and what new is developing with the baby that week, etc. this really wouldn’t bother me but it’s literally an everyday message.

So the other day my husband stopped by her house after work and apparently she asked him if I was mad at her. He said no, I don’t think so? And she said “well she doesn’t reply much to me and when she does she is very short with me” (like I said, I am at work most of the time when she messages me - she also messages me a lot. So yes sometimes I don’t reply but that’s because she will message me 3-5 times in a day. I also don’t find it right to have to talk to his mom more than I talk to my own mom) and she also proceeded to tell him that she is jealous of my side of the family because she believes I post more on Facebook about MY side of the family and not theirs.

She then also asked my husband to NOT TELL ME she told him these things. Which I felt was kinda disrespectful to our marriage. He is my husband, of course he is going to tell me.

So now I’m kinda just upset. My husband does not think this is a big deal which almost makes it worse. But at this point I don’t really want to talk to her or reply to her much at all, especially after she went behind my back and talked to my husband instead of just coming to me. Am I overreacting about this?
