I've been holding a torch for a guy I knew for about 2 years, we've been on an off. We talk and he's been able to move on with his life and I haven't really moved on with mine. I think about him nearly everyday. Try to stay busy during the day but when alone my thoughts drift to him. I still care for him but it's almost like an obsession and even though the last time he told me he just wanted to sleep with me again I am still unable to detach.

How does one get over an obsession? I know it's not good for me and I know others get upset over the fact i get upset when i see him with other women and they see me hurt and get angry with both me and him. Which i know is stupid.

I know this behavior impairs my life- it's obsessional thinking that i try to stop but never fully succeed and when i don't I'm either very sad or angry.

Help?
