I'm Losing my Breath!

Good evening ma,God bless you and your entire family for your good work here.
Please I need your advice at this confused stage of my life,am a girl of 28 years old,I just graduated from the university last year,am still waiting for my NYSC .
I met this guy a medical doctor in July 2013, we have been dating till last year that he asked me of my genotype I told him am AS and he said he heard a story of a couple that couldn't marry because of genotype issue that it occurred to him to ask me of mine that he didn't know his own .
This was happening during Christmas,he called me one day and told me his genotype is equally AS. So I asked him what do we do,he said he has met some of his colleagues to ask the possibility of our getting married,but the answers he got were not encouraging .
So this January he invited me because we don't stay in the same town. I visited him on the 24th of this last month and I discovered that he had another girl he wanted to marry,I saw letters that the girl sent to him,I equally saw his own written testimony of what God did for him last year and the one that struck me was where he said finally God gave him a life partner. And Checking the dates of the letters,he knew this girl even while he was dating me .I also saw packets of condoms which he never used on me .Also saw a drug that helps men to perform very well sexually.
So when I confronted him he said that's the reason why he invited me to let me know that we can't marry and he has found himself a girl .But he was truly sorry that I found out myself,that he was planning to tell me .He begged me all through the night to forgive him that he still loves me and so on .
The next day I left his house,he has been calling and sending messages that he still love me, I should please forgive him. Ma,I love him so very much,and he loved me too and had always respected me. He never in anyway abused me as a woman but I don't know what happened. What should I do? Is the genotype issue the reason or he left me for a medical doctor?
Please I need your advice before I lose my breath.



I may not tell why he left you but one thing I must inform you is that genotype could be a valid ground to terminate a promising relationship.
Your partner was ordinarily a cheat and a promiscuous person but that notwithstanding kindly read more about genotype (Here) so that you will understand the role of genotype in marriage.
So that you don't venture into a relationship with a partner whose genotype is AS or SS.
Please do not lose your breath because of a failed relationship, it doesn't mean that God has failed you but it could be God's way of preventing you from experiencing a disastrous marriage or his way of reminding you that He has a better partner for you.
Hold unto God and be hopeful, all is not lost yet.
