Ex boyfriend died...

I am currently in a relationship of 2 years, and I love my boyfriend.

My ex boyfriend's body was found a couple days ago.

I am at complete and utter shock, sadness, and agony.

It even hurt more since after we broke up, we were still best friends.

I feel so guilty mourning his death since I have a boyfriend right now.. I am still quite sad that he is gone. I just am so... in shock..

Has anyone ever dealt with losing an ex boyfriend?
