Confused

I'm feeling confused. Yesterday my ex emailed me after a girl I know gave him my new email, we previously had cut contact because he told me I kept stringing him along which wasn't true and that I kept messaging him and mucking him about - he was the one who kept messaging me. 

And then again after weeks of no contact he emailed me again! He said how he was confused and couldn't process everything, and that his family don't trust me, but he does... and at the end he put he wanted to sort things out but feels that we shouldn't stay in touch even though I told him before this email there was no us and I wouldn't be in touch again. 

I don't know if he's genuinely wanting to be with me and is confused or if he's just trying to mess with me and is actually a troll sort of person. 

I did like him and had he not been horrible and pushy in the beginning I would have liked to be with him but now it looks like I got a lucky escape. 

I'm just confused that he keeps emailing me and then either wants to give things another go or tells me he'd like to but then says he can't and hopes I understand. 

So confusing and very frustrating!
