Just to relate from personal experience, I caught my former girlfriend of five years cheating on me with a guy who was also at the same time cheating on his girlfriend of three years. I can laugh about it now because it's been a few years but the look on their faces was priceless when I caught them haha... I caught them two in November 2012 and respectfully told the guys girlfriend immediately so she didn't have to find out the hard way like I did. The guys girlfriend didn't believe me and kept on dating him. She later found out the hard way that February before Valentines Day and came crying to me telling me how horrible my ex g/f was. Then my ex and her new boy toy got on me for being in their business... haha Oh it was ugly... ahhh lol! I had enough with the drama and did what Jesus said to do and turn the other cheek. I then sucked up my pride and respectfully gave my blessings to both of them, I mean, what else could be done? lol. During that time it was probably the hardest time of my life and I went through deep depression. What hurt the most before the break up was getting ignored by her. I knew cheating was happening for about six weeks before I caught them but the anticipation of finding out stressed me out more than the actual break up itself haha. But throughout the trials and the filthy pits of hell I swam in, I trusted in God all the way and through God alone learned that every critical piece of what happened was supposed to happen that specific way. Don't beat yourself up too bad, certain crap like that only builds character in your heart and you'll be internally stronger and laugh about your situation later when you find a better woman who respects you. Once a relationship is over, take some time to reflect on what works with you and what doesn't work. All and all you're in good hands when you're in Gods hands, remember that! If I were you I would be friendly under the glow of Gods light but wouldn't start another relationship with her. Even though the dirty deeds have been done, give her your blessing and continue to put your heart into God and good things will come your way. Since my break up I've met and dated a few wonderful ladies, I couldn't be happier right now but at the same time you must learn to embrace the little things. Once you do, you can't go wrong.
