I need some guidance/help

I’ve been dating my current boyfriend for nearly 11 months now (30th will be 11 months). These last few months have been some of the best but of course not without some very low points for both of us. From the very beginning of the relationship I said I wanted to wait till marriage to have sex. My boyfriend was previously sexually active before we started date and I did make it clear I did not want to have sex before marriage for many reasons. He has also told me he wants to wait 10 years before he marries someone, which I completely understand. But now he has said he doesn’t want to wait till then. I’m extremely unsure as to what to do know because I love this man with all of my heart more but I’m not willing to have sex unless I’m married to someone. Please give me some advice!
