My Feelings for my senior!

I find myself enamored with a lady in our office, who is 6.3 years my senior. Her care for me, or so it seems, is profound. She has confided in me the sorrowful tale of her life, and from this, I discern that her husband desired nothing but a child from her. Upon achieving this, he and his mother besmirched her character, subjecting her to such mental torment that she contemplated ending her life. In short, she remains unaware of my deep affection for her, and I hold no expectation that such love will ever be reciprocated. I am resolute in my decision not to marry another, for I am certain that doing so would only bring misery to another, as I could never bestow upon them the love that I bear for this lady. I seek no solution; I merely wish to unburden my heart and share this with you.
