Is it really possible to love someone forever?

Okay, I'm engaged to my bf of almost 2 years, we have a 4 month old baby, and am just so happy to start lives out now as a family, my fiance and i have a good relationship, were always together, and get along just fine, like best friends you could say, after the baby's put to bed we smoke a blunt every night and just kick back downstairs watching tv together, all alone. I wish we could be perfect and happy like this forever, im not saying we don't have our rocky times...we've conquered our fair share of battles. But now days just watching all the statistics, about divorce, and people cheating....(i mean we can't all deny is thrown all around the media), i just don't know if it's really all real. being married. in love. having a family. being happy. I mean, our parents aren't much of examples both couples are divorced. so is it possible at this day and age? to have found true love? or will we be thrown into another statistic in 15 years? if that? by the way were 22
