I have been wondering about you, @Strawberrina, and am troubled by your update. I’m sorry for your pain that your H is still inflicting.
As I feared, you have been in a false reconciliation — conned and further humiliated by this lying adulterer. He chose to throw his second chance into the gutter instead of treasuring it. He never intended to give up his new love, and still doesn’t.
Be aware that his crocodile tears and words of remorse are manipulative Script tactics. Rinse and repeat … you heard it all before on DDay1. His newest promises are actually shit sandwiches, like before. He knows how to play you to make you back down. He believes that you will set no consequences and he will suffer no ramifications for his utter degradation of you and your marriage.
Be aware that he is the driver of his affair. He is not the victim of a wiley woman and he is not a ‘stupid idiot’. He has the power as the superior who decided to have an illicit romance with his much younger junior staff and to keep it going at your expense. He has proven to be a master manipulator.
What is an actual dealbreaker for you, @Strawberrina? He has defiled your life with continued stolen agency, dishonesty, infidelity, mockery, potential STDs, and false reconciliation. He has acknowledged loving OW and has even brought her scent into your home. Still, no consequences. He will absolutely get together with her for cozy dates during his leave.
I suggest that you access IC to examine why you are willing to settle for such contempt and devaluation.
