What happened to you is more reason why everyone needs to know about their lover's genotype when dating because they can't tell where love would take them tomorrow.
Had it been you and your lover have known each other genotype at the early stage of the relationship, you too would have gone in separate ways without getting attached or getting hurt by not being together because of the genotype incompatible(SS + AC).
Its okay to be in love with someone whose genotype is not compactible with yours if you both agree that you wont procreate.
This is a serious mistake most people make while going into relationships; they don't verify these things first and they are very important but there are ways around it if you have made the mistake and you cant bare the loss of your relationship.
What's the purpose of marrying someone if it is not to procreate? God commanded that we should go into the world and multiply. The mistake that someone would do is to marry someone who he knows he's not compatible with just because of love.
