Why did he have to be athiest?

Sometimes, I wish I could just read God's mind, and know what he has planned for my life, because sometimes I feel confused and I don't know what God wants for my life, or even what I want. I had a bf about a month ago, he's really sweet, I could honestly say I loved this guy, in a caring sence. Some that are reading this are like "Whatever Ness, you don't know what love is." I might not know what TRUE love is, but I know the feeling I get when I love or really care for someone. He was perfect, but just one thing really bothered me, he didn't believe in God. No matter what, God is number one in my life and always will be, there's nothing or anyone that can change that. I left him because of that reason because I couldn't go on with my life knowing that we couldn't worship God together. I don't know about you, but that hurts knowing you couldn't do that with the man you reallllllly care for. I still pray for him, that God would just tug at his heart and know that God is real, and just to give him another chance. He use to be Christian, but how can you go from hardcore christian to athiest???!!! I don't understand! I wish I never would of gotten so attactched to him, cuz there's times where I think about him and wish he was on fire for God, because I would of had it freakin made. But God has a plan for me, and I know God has someone out there waiting for me and looking for me. I WANNA MEET HIM ALREADY
