Relationship help!!!

Okay so I've been in a relationship with my boyfriend for alittle over 2 years now and I just recently started snapchatting this new guy, nothing bad just snaps and I've been talking to him for about 5 months now behind my boyfriends back and I'm starting to like this guy but he lives 45 minutes away from me...what do I do? I mean I've been with my boyfriend for 2 years and I'm tempted to risk it for a guy that I haven't met in person that lives 45 minutes away...am I just crazy or what? I'm so confused and I need help... anyone been in this situation? What did you do?
