While divorce is not a fun thing, I'm glad you are choosing to end the wacky.
It sounds like not just a mismatch but super difficult over there. Rather than point fingers at each other -- releasing yourselves from this hurtfulness and allowing you both to seek calm/peaceful living sounds better.
I don't know what kind of support you might need that forum people can offer you in this new journey of yours (navigating a divorce.) But just post whatever it is you may need and ask. Most people are willing to share themselves here and lend support. I don't have divorce experiences but I'm sure other do.
Hopefully every baby step keeps moving it forward in your journey and is taking you to a better, healthier space for you over time. BOTH of you.
