Most marry because they think they are in love I would imagine. I knew I would marry my husband the moment I met him ( depite dating his friend at the time). All I knew was that somehow, someway I would have kids with him and get old with him, so it was going to happen .We decided to marry roughly 3 months after we first met. So I guess we married for love too and for survival. There was no way we could have survived without each other. Messed up families and tied in knots, its only been happy since we were together.
