2 guys....and cheating..

So...I have a HUGE problem, my boyfriend and I have been dating for a year and I'm falling for this other guy who I've known for 7 years but just recently starting really interacting with him, and one night I did something that is considered definetly cheating...I told my Boyfriend everything that happened because the other guy was pushing me to break up with my boyfriend to be with him.. And I was doing that but my BF was then guilt tripping me. I really like both of them and i love my boyfriend, but I feel like I'm obligated to stay with my boyfriend...I barely know this guy and I want to get to know him as friends first before anything else happens...but apparently his feelings are too strong for me and I can't imagine breaking up with my boyfriend after we've been through so much...WHAT DO I DO!
