Do not devalue yourself. Do no make excuses. remember your worth.I do not think you can cheat on a person you love and if you do, you never loved them fully, otherwise, there wouldn't be any voids to fill.
You take love for granted. Just for your own excitement. While we still in our relationship, you're flirting with someone else. You cheated on me. And that's truly hurt. You didn't love enough to be faithful. You do not value that relationship enough.
