<human>: My ex fiance and I were together for almost four years. Supposed to get married this summer. Since getting engaged we fought a lot. It got to the point where I couldn't deal with it anymore and we broke up at Christmas. He still tells me he loves me and such so its kinda weird. 

Last night I went to a party for our mutual friend and of course he was there. Now, he and I work together and all is well during work hours. But seeing him last night I had an emotional break down. I literally hid in the bathroom crying with my best friend. 

I felt so out of place being there because when he and I were together we always hung out with these people. Now its just uncomfortable for me. He asked me what was wrong and then replied "turn off your feelings for a while. Have a drink. Have some fun!" 

I don't know how to deal with this break up. I have a wonderful support system. But now I just feel like I'm not even close to being over him when I thought I was.

Provide a brief overview of the text.
<bot>: looking for advice on how to handle a break up. I thought I was over him - apparently I'm not. :|
