I Can't Believe This Is Happening..?

I know i am going to sound like a slut..but im really not. I have been dating this guy for 8 months, and i really love him. He was my first and everything. But last year i fell in love with a guy named Devin. We have a really strong connection..Although we never dated, we made out, like everyday. Then we stopped talking. And i started dating my current boyfriend..Then Yesterday i did something horrible...i cheated on my boyfriend with Devin. I feel quilty cause i love my boyfriend..but i couldnt help it. We just made out and he fingured me....I know cheating is never right...and that was the first time i had done that..Please help me..I love my boyfriend too much to hurt him, but i cant stay aways from Devin :(
