First off. Love doesn’t exist on a biological scale. It’s crazy to think that something that we get attached to so much it brings people to end it all if their lover betrays them. I guess it’s just the way humans work.  My opinion varies. I believe that love at first sight doesn’t exist, love takes time and love takes work but, if you have a gullible person who’s very optimistic and willing to do anything i believe it’s possible. It all depends on who your with some people are willing to settle down right away and go off and get married, but others don’t do things so quickly, especially after a past relationship.
