Welcome!!
I'm saddened by this seemingly trajic "trend" that seems to be popping up with the witnesses. I too know of someone who has an ex and is seeing someone "worldly" on the side. No one else knows. Like a dirty little secret you said. And what have you done wrong but fall for him, which in itself is not wrong, but what is wrong is the way that you have been strung along. If there have been intimacies between you, and he has been lying about you all along, he is also not telling anyone about that either. He must now keep clean!!
I feel for you, because you are the one that is paying for this fraud. The heart can be a hard thing to protect, and just when you thought it was safe to go into the water again a shark appears. I know this is not what you want to hear, but beleive me and everyone on this board, you are so much better off without the lies and secrets. You obviously deserve better. Take care and let that wound heal. And if he comes around again to cop a feel, ask him if he is going to confess to the elders later!! ha ha he'll probably poop his drawers. Smiles for you.
