I need advice help.

Recently I've gotten into a new relationship and I told my boyfriend that I was in an abusive relationship and that I have PTSD. We kinda talked about it but he didn't really want me to go into details. 

Last night I went out with my friend and she told me that my ex has been stalking me via social media. This scared the crap out of me and I told my boyfriend right away. I ended up having too much to drive and He came to get me. I was overwhelmed with the fact that he was stalking me and a babbled about it. 

Today he told me that he thinks that I have a lot of things to work out. And I told him that I thought my ex was out of my life and gone. He said that I talk about it too much and that it makes him think that I'm not over him and that I'll never get over this. And that he can't change it. And that he has somethings he needs to think about. I told him I'm completely over my ex.  And that I am getting over the abuse and that he's helped me so much. He said he just has somethings to think about now. I'm giving him space and Just waiting for him to come to me. But should I be expecting a break up? We've told eachother that we love eachother and that we really want this. I just don't know what to think. Bless you if you've read this far.
