first proper relationship

I am in my first proper relationship at the mo it has been about 8 months. We get on so well but we also work together. I just feel so jealous and pariond it has only recently started, but I hate the feeling and wish I could just get rid of it as I always said I didn't want to be this type of person. It is all new to me as this is my first REAL relationship. I don't know how to deal with these emotions that I am feeling now. I couldn't imagine him not being in my life now as we have done so much together, I know I am the one creating the problems and its so annoying!!

Thanks
