When it comes to relationships, we often focus on personalities, shared interests , and values as a foundation of a strong connection. With the recent complications in marriages due to blood incompatibility, it has shown that genotype and blood grouping also play a significant role in shaping a successful relationship. So among other factors, knowing one's genotype will help them make good decisions in choosing a life partner.
A friend of mine had done his marriage introduction when they both realized they were all carriers of "S". It was difficult for them to go their separate ways after the realization. They call each other at night to either cry or encourage themselves to take the risk and my young friend who was even a medical personnel almost succumbed to taking the risk with the hope that God will intervene. I understood his pain, sometimes it's difficult to cut off from someone whom they've shared their dreams and plans with and sometimes someone who had made them smile over the years. At one point my friend told me He wouldn't get married in life if he didn't marry this particular lady. I knew this statement was out of emotion. It often feels as if there's no one else who can fill the space and this is how powerful love can be. Luckily, time healed them and they were able to find love again.
Contrary to what the medical friend of mine did. My childhood friend happened to be in the same situation. He had always believed he was an "AA" because his both parents claimed to be "AA" even though there was nothing like blood test in their era. So he entered a relationship with such an assurance until a few months to his wedding when the church asked them to go take the test. To his surprise he was an "AS" and his girlfriend too was an "AS". It seemed as if the love had gone far, to a point where it was unbreakable, because they went ahead with the marriage regardless of the thousand and one talks I gave him. His parents were not knowledgeable about the implications of incompatible genotype, so didn't know the implications of what their child's decision.
My advise
One thing I told my friend was "Love Isn't enough when peace is absent. The life of a child matters too and it's wickedness to bring a child to the world to suffer in the name of love". Sometimes it's not about us, it's about the impact one's action will have. Love isn't greed, even the bible says love does not rejoice over evil and when we start to think about "us" alone, then it's no longer love but greed.
And for people who had taken the bold step to end the relationship. I will say they've taken the best decision, because at the end, regrets often follow if God doesn't intervene. There's always someone who fits in our values and personality traits. All we have to do is allow time to heal us just as it did with my friend from the first example and for those who are yet to enter a relationship or yet to take things seriously, just before things get too intimate, it's safer to know your genotype and blood group to avoid a hurtful scenario.
