So: my boyfriend and I have been together for 3 and a half years. Recently, though, I have been reconnecting with a friend from my freshman year of college (I'm a senior now) who I've got a bit of history with. We've been snapchatting, no pictures, for a few weeks now and I find myself enjoying it. I like the excitement of talking to someone new. I feel SO guilty though. Am I cheating on my boyfriend because I am enjoying talking to someone? I feel super flirty but I just can't stop it. Anyone have any thoughts or advice?
