Napoleon to Josephine

I wake filled with thoughts of you. Your portrait and the intoxicating evening which we spent yesterday have left my senses in turmoil.
Sweet incomparable Josephine, what a strange effect you have on my heart!
Are you angry?
Do I see you looking sad? Are you worried? ...
My soul aches with sorrow, and there can be no rest for your lover; but is there still more in store for me when, yielding to the profound feelings which overwhelm me, I draw from your lips, from your heart a love which consumes me with fire? Ah! it was last night that I fully realized how false an image of you your portrait gives!
You are leaving at noon; I shall see you in three hours.
Until then, mio dolce amor, a thousand kisses; but give me none in return, for they set my blood on fire.

Bonaparte

I hate Napoleon for some reasons.

Like, he left Josephine so easily and had an affair with other women and said something like 'power is my mistress'. Damn, he's such a jerk (sorry but I don't think I'm wrong). After all those sweets love letters, with romantic words and sounds like he truly deeply madly in love with her, he left her just like that? Because she can't pregnant?

I hate that kind of person who can forget the love so easily. I mean, Josephine was his wife! I absolutely could understand if you love someone and they don't love you back so all of your love letters (or some kind like that) is wasting.

Am I wrong to think that someone could never stop love someone else who love them back, somehow? Cause in my 18-years-old life, I don't think I could make it. It took a very long time for me to move on from a guy who don't even care about me. And I can't imagine if my heart could change when I love someone and somehow he loves me, too.

Well, I'm sure Napoleon was the opposite side of me. Maybe he's got he's own reason. Or maybe I'm just too naive.
