You're capable of loving more than one person during your life time. I don't believe in this "you only have one great love" I believe that there are many people out there that you could fall in love with and it just depends on which one you meet and end up with. And if that person dies, then there is still more people out there that you can also fall in love with and that doesn't mean that first relationship meant nothing, you can have room in your heart for more than one person and that's fine.

Most people would want their spouse to move on after their death. Wanting them to remain lonely is just selfish thinking. Also isn't "till death do us part" the promise? You're dead Now so I gotta go my separate way!
