I have been warning my bóyfriend about this particular girl he always chat with. When we started this relationship he promised never to cheat on me but after 2 years he started flîrting with one girl he met on Facebook. I confronted him but he denied, he didn't know I saw their Whatsap chat when he was slëeping. I screenshot their chat when he was telling her how good she is good in bëd 🛏️ I showed him and stated quarreling him, he beat me up and told me never to go to his phone again. I want to leave him but he promised to see my people before this year ends, I'm confused and need advice. Should I leave him or should I stay and pray that he changes?
