My ex was horrible to me.
How was he horrible to you?
He was a lazy bastard that would always sit around and say bad stuff about me.
You should have broken things off with him as soon as his attitude towards you changed. Don't feel forced to stay in a bad relationship just because you've known someone for a long time.
Our relationship was not meant to be. If he didn't want to split with me, he should have just made an effort to improve our relationship.
I am glad you are no longer together with this horrible person. You can now begin to focus on yourself and heal. In time, you'll find someone who treats you with the love and care you deserve.
