MA, very sorry to hear this. However, it is unfortunately predictable. So many LBWs try to fight fire with fire. WAH is sleeping with someone else so I'm going to compete and sleep with him even more!
All that does is feed a WAH's ego. So many guys fantasize about juggling multiple women. Most women do not want to share a man.
A couple of observations:
First, he sent her the text because you made him. That never works. He did what you wanted in front of you, then did what he wanted behind your back. Please understand, there's nothing you can do to get him to end his affair, he has to want to end it himself.
Second, go back and read your last post. He said. He said. He said. Remember, believe nothing he says. Nothing. He will tell you what you want to hear. He'll tell you what is convenient at the time. One thing he will not tell you is the truth. Cheaters are willing to do the most despicable thing in planet earth: cheat on their spouse. So lying is not even a second thought to them. If they'll cheat, they'll lie without fail.
Third, please schedule a doctor's appointment at your earliest convenience. You had sex with him while he's still having sex with her. Anything she may be carrying STD wise you are now at risk for. Do not jeopardize your health. Hi get checked out and then stick to your vow not to sleep with him until you know for sure his affair is over.
MA, refocus on good DBing. That's your sweat l way forward.
