Is it an act of courage to let someone know how they make you feel?

I recently had to let someone who has been in my life for a year know how devastating they make me feel every time I hangout with them. We are two completely different personalities. I told him that I couldn’t get rid of this concerning feeling in each encounter and how I won’t feel good going to bed tonight. He doesn’t want me to be in his life and he made sure I realized that. I just can’t seem to move on, and I let him know this verbally for the first time, two days ago.

I just tried to be real. I couldn’t act cool and pretend like I’m fine when I would feel awful after we meet, as I always do.

I believe I am obsessed and I suggested him that. We talked for about 3 hours straight and I kept it going because I was afraid of leaving the restaurant and going home to then feel devastated.

This was the goodbye, but it also was a twisted confession on my part. He thinks I am quite crazy and wants me out of his life, and I made him realize how obsessed and sad I am which is something I never confessed to before. Truth has come out. Before, Id pretend like I’m the cool thing who is decent with everything related to him, but would be destroyed when Im on my own. Do you think it was brave for me to leave my pride and ego aside and tell him how him rejecting me, and him being in my life overall had an awful influence in my personal health? I simply wanted some kind of sympathy/help from him… I felt hopelessly imprisoned by the obsession. We did leave on good terms but I was anxious and revealing throughout the talk as I never have been before.
