Cohabitating vs. Values, Beliefs and Religion

I have been dating my bf for several yrs now and we have been in a long distance relationship. However, he is in the Navy and I'm finishing school actually masters. I want to pursue my doctorate but I'll need to  move out of this state. The point here is that my bf is station in California for several yrs and told me to move in with him. Honestly, I can do it and applied schools in Cali but the problem is that (he already knows this) I don't believe in cohabitating before marriage. As a Christian woman, I will like to get marry with him later or when the time is right and he is not in deployments. He told me that this is not cohabitating per se since he wants to get marry with me soon. I believe him but I also feel that this is not the right thing to do. My parents in the other hand agreed and remind me that if I plan to cohabitate I'm breaking their values and God views. I'm 26 and he is 24. I know I listen to mynaprwnst but they are imp in my life. Any advice?!!!
