I would have to say if you told her you were uncomfortable with it and she kept talking to him, or she wouldn't let you see what was being said yes. I don't think thats cheating b/c she wasn't responding sexually but I do think she was wrong and I would have been hurt for even responding and letting the "long, sexual texts" go further than 1. I found my self in a similar situation recently except that I found that some slut, who knew he had a me, send my bf nude pics via cell phone. he kept them b/c he thought they were the same as porn. this made me really unhappy, it wasn't cheating but hurt me. we had a long talk about what is and is not cheating and he did admit to "kind of having cyber sex" a few months ago. I DO consider cybering cheating and again he things of it as just a form of porn. he know it upsets me now, and has promised not to do it again. We are working on things but its going good, still if I found out he did it again or find dirty pics that aren't real porn or of me we are going to have a major problem. did that answer your question?
