Hi Praguer,
I feel your pain. I was in a very intense relationship a while back that ended painfully, and put me in the hospital because I felt I couldn't live without this person. He got in touch with me shortly after I got out of the hospital and just when I felt like I was doing better. I started seeing him again, cautiously at first, but then started having high hopes that things were going to work out. He wasn't able to commit to me fully though, and I had to severe all contact. It took a long time for me to get over him, but now I am finally free and in a relationship I wouldn't trade for the world. I think if you break all contact it will be much easier to get on with your life, and in time you will heal and find the person you are meant to be with. I wish you well, you deserve happiness!
Love,
Sujin
