I already have a boyfriend when I met this guy, and we instantly became friends. We would constantly talk about anything under the sun. I never liked him as anything more than a friend. It's just that he was fun to talk to, and I can always rely on him for sound advice about anything. My boyfriend accused me of cheating on him with the guy even though he has read our conversations which don't imply anything. He, on the other hand, is best friends with his ex and they also talk on a regular basis, and I don't accuse him of anything.
