will we last till the day we die? Me- girl rat June 13,1984 & He- male rabbit august 8,1975

Been together since Dec.31,1998 & have 2 children; boy age 16 born Oct.31,1999; girl age 13 born April 30,2003. We've had many ups & downs. We either get along Great or Not at all. I feel he used to love me so much more in our early years together! We married Sept.12,2003 soon after my daughter was born. His family never liked me & we've been living apart since 2010 after I was injured badly at the end of 2009. Since then we're not been close like before. Will we even get that spark, or connection we used to have?
