my fiancé broke up with me....

Josie
So, my fiancé broke up with me 2 months ago and we were together for 8 years.... Anyway, he already has a new girlfriend and I'm so heart broken. I don't know what to do except move on myself cause I think maybe it will make me feel better. Anyway, so what I'm trying to say is I've been out of the game since I was 15 years old so I don't really know how to start up a conversation with someone. I'm kinda stuck... Please help
