God turning someone straight?

I found myself very puzzled yesterday. There is this guy at one of the Bible studies that I attend that I cannot seem to figure out. I always give people the benefit of the doubt. A lot of times I am more trusting than I should be and give people way too many chances. I am optimistic to a fault. This guy, who we will refer to as one, just boggles my mind. I cannot seem to put my finger on why I do not trust him. It takes a lot for me to not trust someone. It bugs me that I cannot figure him out. A friend of mine was telling me a little bit of his history. One used to be a party guy. He used to do drugs and I think drink alcohol. My friend said he was gay but when he found God, God made him straight. And there it was! This is what I could not put my finger on. I know God can do anything. I know he can work miracles. I have been a Christian my whole life. However, if one was happy being gay why would God change him? My church is very traditional but, in general, very liberal. We are accepting to everyone. We do not pass judgement because we know that is not our job. I try to not pass judgement but I am not perfect. Of course sometimes I slip up. Sometimes I sin but that is okay! God loves me enough to forgive me. I have never had a problem with someone being homosexual. I know it is a sin. I also know that God forgives sins. He forgives mine and he forgives theirs. I am struggling with this. I cannot figure out why God would decide to make someone straight. I have been thinking hard about this and, no matter how hard I try, I cannot make sense of it. I am a hopeless romantic. I believe that you cannot help who you love. I believe that in this world there is that one perfect person for you. I believe in that gushy true love that is in chick flicks. I prayed about this last night asking God why he would just make someone straight. I am seeking an answer because nothing in my breadth of knowledge makes sense. Perhaps someone else can make sense of this? The only thing that makes sense is that God knew one was not happy. He knew that one was seeking something else. He knew that one could have a better and happier life. He knew that one's party life was contributed by his unhappiness. He also knew that by turning him away from homosexuality he would be able to lead a better life. I guess this makes sense.
