AIO Wanting to divorce

My wife (F32) and I (M34) have been together for 7 years and married 5. Before we even entered into a relationship I explained to her that I NEVER want children, and was firm on that choice. I have her a few days of thinking and she agreed to this.

We generally get along well, but there have been periods where she'll get emotional, confrontational, and very critical. This culminates with her expressing that she has regained the desire to have children. After a week of hearing her out and explaining that I love her, but still do not nor will never have children, she moves on and things go back to normal.

It finally came to a head this last round, where we discussed divorce. She decided to take a few days to think about it. (Ended up being ~a month). I approached her, asking if she had thought about her decision. She explained that she's content where she's at, and could be happy. I asked her what she'll do if she gets the urge again. She said she'd consider divorce again. She also explained that she may not be able to foster intimacy since I won't give her a child.

I can't see myself staying in this relationship knowing she might walk away at any point in the future. It feels like being next to a bomb that you dont know when it will explode. Intimacy has been less than what I want, and I only see it getting worse. On top of that, although she's entitled to change her wants and desires, and thats OK, I feel as though my opinions and desires were never fully respected, as she thought she could just change my mind on this issue.

AIO for wanting to leave my wife so that we can pursue what we really want?
