Here's a revised version of your message in proper English:
"Look, I understand that I may have changed in some ways, but that doesn’t mean I’ve stopped loving you. The reason I haven't been able to communicate with you is that there are a lot of things happening in my life that I can't talk about. You know that I sometimes struggle to express what's really bothering me.
As for Mash, I'm not dating him, and I have no intention of ever dating him. Whatever is happening between you and him, I wasn’t involved, as you might recall. It feels like you’re picking fights out of nowhere, and I find that hard to tolerate.
If you choose to ignore me, that’s your decision. Goodbye, Mokete. I wish you a great life."
