He cheated with me, but loves her?

This guy (brett) and i had been talking from February to now. Me and him had a thing for a few months and then started liking my best friend. My best friend had a boyfriend and broke up with her boyfriend to be with Brett. I cut myself when i found out he liked her. I was in love with him. Even though he and my friend had a 'thing' he still said a bunch of things that girls LOVE to hear. Brett and i live less than a block away from each other while my friend lives 20 minutes away. Me and Brett snuck out and talked and stuff while he had a thing with my friend. We snuck out about 5 times. Each time, we got closer to each other. The 5th time, Brett and i made out. 5 days later, he and my friend officially started going out. I loved him and even told him so. While they were dating he said those things a girl wanted to hear and even told me that we should have had that night we made out. Then, about a month and a half later, Brett and i snuck out again. We made out, he felt me up, rubbed my , and almost fingered me. He cheated on my friend (who wasn't really a friend since she started having a thing with him). I told my 3 best friends who i'd trust with my life. My best friend of them all, told my friend what me and brett had done. It became a big drama and now most of the school calls me a skank and blames me, but yet, my 'friend' took him back and he got away with cheating on her. He was the one who came to my house, he was the one who kissed me, he was the one who touched me, but yet, im the one who is suffering. He told me that he would pray every day that i would die for telling the truth about what we did that night, and now he wont even talk to me. I dont know what happened and i just want to know what i should do now.
