my ex-fiance died...

whoa guys i don't know what to do. my ex fiance's girlfriend (the one that he cheated on me with and had a baby with) came to my house on saturday. at first i thought she was gonna start problems, but she instead told me that my ex had died the night before. i was in shock. i didn't know how to react. we had been together for 5 years, and were ready to get married. unfortunately, he was not a great guy...actually he treated me very badly. even though we left off on not great terms, this still saddens me. the last time we talked, i told him that i forgave him for all he did to me, and that he needed to move on. so i'm glad that i atleast got to tell him that i forgave him. now the problem lies on the funeral. i don't know if it'd be proper to go. i dunno, i'm just so weirded out by all this. part of me is really sad, the other part is just numb.
