The Pain is too much to bear

I'm in my late 20's. My first and only boyfriend of three years went out of the country to work. He promised marriage when he comes back.

However, when he came back after two years, things changed. He took me for granted and later dumped me like a rag. I attempted suicide, but his comfort overshadowed my pain.

How can I forgive him? I trusted him so much I gave up everything for him. The Bible says that we should not hate our brothers or else we become murderers. I want to forget him, but the pain is too much for me to bear.
