Let me hip ya'll to something. Players/competent cheaters are some of the sweetest people you will ever meet. Every time you are in their presence, it is fun and games and everything is wonderful. When you're not around, they're bringing that exact same experience to other people. Thus, when they cheat on you and you find out, you don't want to have those wonderful feelings that you've become dependent on out of your life and they will be right at your doorstep gaming you, putting on the tears, promising how much they've changed.
in your own mind you start thinking you can rekindle that fire and that it was just an honest mistake and that person really loves you. This cheater is thinking let me see what i can do to get ma back on my team... he might even be laughing at you in the background. if he is sincere, the sincerity will last only about a month before his natural habits resume and he's right back to talking to all these females.
people operate on habits. The same habits they had before they met you is the same ones they will likely carry on into the relationship. Cheater/player/womanizer before they met you, cheater/player/womanizer when they get with you. One of the worst things a woman can do when entering a relationship is thinking that she can change a man and treating him like some project. On the surface, it may seem like you are causing change, but it will last only a little while before they revert back to their natural characteristics.
If you get back with this guy, you are essentially rewarding him for his cheating and giving him the impression that he can always pull you back in. What do they say? Treason is punishable by death? There's a reason traitors are treated so harshly. What did Jesus tell Judas? "It was better that he was never born."
Relationship treason needs to be punished by eliminating any second chances.
Without any repercussions, people will continue to engage in their sorry behavior. Let me be perfectly clear with you. Someone that really loves you will have enough consideration for you to not cheat on you. Players, on the other hand, know how to manipulate your emotions and make you feel great and will constantly manipulate your emotions to pull you back in while they are doing their own thing. If you choose to be part of that cycle, you have been warned. There will be nothing but an emotional rollercoaster of pain and misery interjected by brief moments of pleasure deriving from emotional manipulation in your future... but the ride will end with a calamitous drop.
