* He was in a 2-year relationship with a girl who he describes as somewhat crazy, and from the sounds of the stories he's told me, his parents nor certain friends were not entirely too fond of her.  They've been broken up since July of 2011, and he and I started seeing each other End of February 2012.  
* A lot of our relationship-esque conversations involve a lot about his ex, and even while we were chatting at a pub just last week, he received an email from her, which he offered to let me read (I declined) -  but told me that they call/email once a month since they didn't want to just throw away their friendship. (Reasonable part of me says that's really lovely and mature, insecure part of me worries)

* They're not friends on facebook, and he assures me that he would never go back with her.  

He also recently told me that in talking to  Well, hearing that was like a punch in the chest but I'm glad he's open with me, and he did tell me that he told them he's not looking for that.
