Well if they split due to a divorce, then were they really soul mates to being with?
As for getting married again, and loving the new spouse even more than the other one…I think it may be because you’re at different stages in your life. So what you had with the first spouse may have been totally different than what you have with the second.
Sometimes I think people perceive a soul mate to be someone that they’re in love with, or have a great relationship with. I think that it goes above and beyond that. It’s more than just saying ‘i love you’ or buying gifts for each other. It’s almost a mental/emotional thing, where two people ‘click’ and get along through anything obstacle that comes their way.
