<human>: I was with my ex-boyfriend for three years. Overall it was a very toxic relationship, both of us dealing with mental health issues and constantly breaking up and getting back together. We would constantly fight, and there were instances where he would shove me around and call me names.

It's been three months since I decided I finally had enough, and today he called me and left a voicemail saying that he was going into a mental health facility for a few months and gave me a number for contacting him while he's in there. 
In the voicemail, he mentions the time that I had a mental breakdown and was hospitalized. During this time he drove an hour each day to visit me and be there for me. 

I want to be there for him, but in the past every time we have cut contact and started contact again, we end up getting back together. I do NOT want this. I've always wanted to remain friends with him but he has an "all or nothing" type of attitude. Towards the end of our relationship he was very mean to me, and even stole a laptop from me. However, I still want to be his friend and support him through this but I am worried how it will end. Should I ignore the voicemail and keep him out of my life? Or should I be there for him during this? I know that he has almost no friends, and besides his mom no one will be there for him during this. It would suck to go through this alone, which is why I am conflicted. Please help.

Can you give me the gist of the text in a nutshell?
<bot>: My ex contacted me saying he is going into a mental health facility. He was there for me when I went through this, should I be there for him?
