Am I wrong for this?

My husband and I have been together for 4 years and married for 2.5 of that. He has been extremely abusive. I left him on the 2nd of December and moved back home four hours away. He went to the doctor and was diagnosed with some mental disorders which caused him to be violent and short tempered. He has since been on medicine and has been wonderful. He feels like I left him to get help on his own and the I should be there supporting him however he doesn't blame me for leaving. Because of the efforts he's made I agreed to come back home on Christmas which will mean that I have been gone less than a month. Since I've been gone we have face timed constantly and we read the five love languages the book together while taking turns reading over FaceTime. Is it wrong that I feel like there is a 1 month requirement of me being gone? I would be a moron to just rush back right? I feel bad because he seems so sad! P.s. When I say abuse I mean every kind you can think of. He has not beaten me to a pulp but it was only progressing to that. And I have been spot on and called every name you can think of. Based on being a Christian what is acceptable for me to do?
