I need advise please

My boy friend 52 and I’am 40, we have been in long distance relationship for a year now, we met online and I never saw him in person. I love him he loves but we both from different religion and both of us don’t want to convert, I want to merry him, but he can’t convert. I wanted to Breakup with him, but when i did We couldn’t stay not talking and far from each other more than two days, we returned back and he is telling me to wait for him up to five years as he is hoping things might change by then. I feel that I don’t want to waist any day a way from him, but it seems he want us to stay like this until I don’t know when. What your advise to me will be.. should I wait? Should I leave? Please tell me what the right thing to do.
