Why is my ex still talking to me?

[Lia]

We were friends for a year, started getting flirty and dated for a few months. He changed my whole personality and was manipulative. Being with him made me really depressed and I didn't know how to get out of the relationship. He pretty much sexually assaulted me, and I felt trapped. He caught me when I wasn't feeling the best about myself and took advantage. He broke up with me over something I wrote on twitter.. I just retweeted something saying "I really don't know if you want to be with me or not" And he flipped. We didn't talk for two months and I started gaining self confidence and feeling great. One day he messaged me and I just broke down. I felt like I was passed all of the depression and everything. We became some what friends again and he apologized. He started flirting with me again about two weeks ago, but I just ignored it. I realized how much better off I am without him and I haven't texted him back in a week. Should I just stopped talking to him completely or give him another shot at being friends?
