What needs to be considered when ending a marriage?

We have been married almost one year, and its just not working out. I don't see it lasting long term.

He has two cats, and I have two dogs. No kids involved.

We own a house with a mortgage, and in the past he has commented on keeping the house.

My parents live in the same town as us, and his are approx a 2 hour drive away.

He has a tendency to lost his shit, and become irrational, so I will make an appt with my therapist on how to broach this with the husband, and how to deal with the fallout.

Any and all advice very much appreciated.
