stretched thin

what do you do when ur heart is stretched thin and you feel the guilt set in an obsession for many men when u really wish to marry him but your heart loves to many that u can't control a feeling like the ripping of your soul I hate myself for having a heart so big I hate myself for falling for another one again when I already feel the tug of my heart stretched thin how do I explain it to him that I can't control this feeling within how do I explain that this was always worth the pain
