I’m in a really good long term relationship. Happy. No issues. He’s amazing.

But recently I’ve become too close to a male who I’ve been friends with, now we both have feelings for each other. We don’t meet in person but over the phone there is SO much sexual flirting. I feel like I’ve fell into the good guy and sexy bad guy scope and I feel so guilty everyday that I’m not being honest to my partner but I can’t stop! I wouldn’t do anything physically with the other guy but there is just something about it and I really don’t know what to do. I would always choose my partner over him but I don’t know how to drop the other guy. The excitement has me hooked.

Am I a horrible person? What do I do? I can’t talk to anyone so I’m here for desperate advice
