My mother-in-law lost over 50 pounds and now thinks the world revolves around her. I truly despise the person she's become and the fact that she blames me for how our relationship is souring

She's been losing weight on Ozempic starting about two years ago and since she lost 50 pounds (now it's close to 100 pounds), has become insufferable. Every conversation is about her and how fabulous she looks and how her "new life" is so exciting. Any time my husband or I try to talk about something new or exciting in our life (including her grandchildren) she cuts us off, interrupts us, or talks over us to talk about herself.

I recently completed my master's degree but she has no idea because any time I tried to tell her I was even in university, she interrupted me or talked over me. My husband has also tried to tell her but she is so self centered, she can't let us even talk for a second unless it's to answer a question she's asked. He says her loss, she's not getting invited to my graduation and celebratory dinner. My father-in-law left five years ago and hasn't been heard from since. He doesn't even know he has grandkids.

Now she's saying we have problems communicating and that we're purposely leaving her out of things. We started recording conversations with her and showed her just how she treats us but apparently it's OUR problem because we don't try to talk again. We do. We used to tell her she was interrupting and she would say things like, "Well you didn't shut up fast enough for me to talk." We used to tell her how rude and self-centered she was being but she didn't care.

I told my husband I want nothing to do with her anymore. Being around her is frustrating and it feels like I'm watching a documentary all about her life. She doesn't ask me how I'm doing unless it's something like, "Why haven't you taken me out to dinner yet? You used to always take me out to dinner for my birthday."

It's frustrating because we used to be so close. I tried writing her letters or sending texts but she just ignores them or says "I don't read mail unless it's important." Ouch much?

I don't even know what else can be done. My husband says clearly she's happy alone and we should just cut her off but our kids love her and don't know any different about her behavior. I don't even know where to start.
