What to choose; Jesus or ?

My boyfriend and I have been dating for about 9 months now and I love him dearly, and yes we have had already. My problem is, I have been suddenly hit with a bunch of guilt lately because I am a Christian, but I'm going against my moral ways by having premarital with him. I feel like a hypocrite! I just told him that I feel we should take a break from , and talk it over and such, and he just like flipped out on me. Should I give into temptation and continue these sinful ways, and just ask for forgiveness? Or cold turkey? Thoughts, please?
