questions for the ladies.

So, I've been with this guy since 2014 we have had our ups and downs. He has been very violent in the past to me and we have a 7 month old and last night he got mad because I was upset about something work. He said he was tired of it and then ended up throwing pictures off the walls and telling me to "go be the slut I used to be" so I left and stayed with my mom. I was holding my son and seeing that really upset him so that's when I left. . He's bipolar it seems. One day we are good and the next, stuff like this. Any advice
