I posted this in the "Welcome" section and was directed here, so here it goes...

Late last year I started going out with a guy I work with. I'm 18, and he's a lot older than me, but I thought we'd try it and see if it would work. Because of the age difference, we had very different expectations. He was looking for a life partner, while I was just looking for someone to have fun with and maybe be with forever. I loved him, but last month I broke up with him. I did that because of my anxiety. Ever since I started going out with him, I would wake up in the morning feeling nauseated and usually vomit. Then I would also vomit if we went out or I thought about going somewhere with him. This went on for far too long and I'm ready to be done with it, but because we work together I see him almost every day. And he's said that he still wants to be with me, that he'll wait for me, etc. I finally told him that we're not getting back together, and I feel pretty terrible about it. But I know that's what's best for me-- though I do wonder sometimes.

So now to my question: What do I do? How do I get over this guy when I see him every day? And how do I get over my anxiety?
Thanks for any advice!
