My boyfriend messaged another girl on Facebook. He said some sexual stuff to her. Has he been cheating?
I would have to say Yes, also. He may not have been physically cheating, but talking sexual things on Facebook would be pretty close. Confront him about it. Doesn't sound like much of a boyfriend. You might start looking around for a loyal boyfriend.
It depends what you refer to as cheating. Are you a strict girlfriend, or are you forgiving and more lenient. I for one am a pretty hard on my boyfriend and I consider sexually explicit conversation "cheating". No bed needs to be involved. If he has a sexual desire for someone else, he is being unfaithful to you and may not have been with you for the right reasons to begin with. Do it to him and let him see how it feels, I bet the first word that will fly out of his mouth is "cheater". Good luck!
