I'm finally getting the divorce I've wanted since 2014.
Why have you wanted a divorce for so long?
My husband is emotionally abusive.
That sounds like a bad marriage, so it's good that you're ending it. I hope that you can find a better partner next time, or that you can be happy as a single woman.
I'll probably try to rush things by having an affair with a new partner.
I can understand why you want to get out of this marriage as soon as possible, but having an affair now is a bad idea.  Legally, you could put yourself into a weaker position during negotiations if your husband can blame you for infidelity.  Furthermore, rushing into an affair could leave you with another abusive partner.
