Need prayers & Advices & inputs on relationships

My boyfriend and I has been dating for 5 years now. The problem is that I am a believer of Jesus Christ and he is not. Our relationship as of right now is still really strong, and I feel like he is the one that God sent me to. I am a Christian all my life and just recently a reborn Christian, and has been serving God’s will for 3 years now. Everytime when I ask him if he would be a follower of Jesus and believe in him, he would always say that he is not sure, and will see what the future brings us and that he still has a lot of time to think about it. I just have to say that I believe in Jesus Christ and his words, but this man that I am with seems to be the right one. I really need your prayers and advices. I am not sure what to do with life at this point. I know that they always say if you believe in him, leave all your sins behind and whatever is sinful behind and God will give everything you need and want when you enter into his kingdom. I don’t want to regret anything afterwards. I am so lost, confused, stressed and scared right now. Should I just let go of everything and be a follower of Jesus Christ??? Should I just run from everything and start a new life with Jesus Christ?? OR Should I just stick with what I have now and wait for what the future will bring?? Please help. Thank You and God Bless!!
