I recently had to break up with the one I love because I don't want to hurt him anymore.
Well that was extreme. Why don't you try to work things out?
I don't want to see myself or him suffer anymore because of me.
It will be difficult moving on but it's understandable to break up with someone you are hurting. Staying together with him would have only led to more suffering.
I moved on, I'm already seeing someone else already.
It's good to hear that you got over the break up. I hope everything goes well with this new relationship.
