Why does he jeer at me?

How could he do this? We always shared everything with each other. We always could discuss everything and find the decision together. Three years of the all-absorbing happiness are crumpled and thrown away in a dustbin. He became unfaithful… He found another woman. At his work. Well, of course, every day before his eyes… He lied for two months, “worked on two fronts”, was growing thin, old, started smoking.

Well, let it be so… I got used to tears, lump in my throat became customary.

Many things can be understood. Habit, family life, rut, one wants infatuation and fireworks of emotions. But I cannot perceive the following thing – He says that needs me and that I am precious to him as before. But SHE is precious to him as well! He says that I am his dear and close person, that he cannot imagine his life without me. But she is the woman he is in love with. And I… I am the part of his life, inseparable part.

Why does he jeer at me? I think it’s easier to die rather that stand all this…

I need your advice, people…
