I've cheated on my partner a few times before in the past, but now I want to stop because she says she will leave me if I don't. I don't want to do it again, but I know my weaknesses, so I'm not sure if I can really stop. How can I stop cheating on her?

If you truly love her, you wouldnt cheat on her. You want to stop just because she will leave you not because you dont want to hurt her anymore. What kind of bullshit is that? Man up and leave her at peace. She doesnt deserve a trash like you. She deserves someone better and far from who you are!
