To some, that's the perfect time for revenge. I've not been in that situation before, and I pray not to be cos it's not worth my precious time and energy.
Yes, I've been hurt badly before, but I never allow it get to hate. I just think that whatever the situation that made your love-life go sour, you should just learn to forgive and let go.
This life is too short to carry such heavy load(hate) around you, don't waste your time getting bitter. You should let bygone be bygone. There are better things to do with that beautiful heart of yours than to allow hatred take over.
Let love in and hate out. Don't get it twisted, Love is a beautiful thing. It is light, it brightens everywhere. Let us allow it reign in our hearts, home, world. Love is you and I. Love you guyz! Cheers!
