Here’s a revised version of your message in proper English:
"I never thought I would see the day when you would discuss my pain, turning it into something I don't quite understand but can only describe as a comparison. You really knew how to break me this time. If you knew you were going to react this way, you shouldn't have let me feel comfortable enough to open up in the first place. The reason I didn't want to tell you what was bothering me is that I knew one day you would make a joke about it or use those words against me.
I've never truly enjoyed my relationship with Paballo, and I'm at peace with that because it shows that he wasn't the right person for me. However, when you said, ‘That’s why Paballo treated you the way he did; he saw right through you,’ you really crossed a line. I have been kind to you; I loved you, Kabelo. I took you as my everything. So, it’s fine."
