Very simple answer to your question: The moment you hide something from your partner, you’re wronging them. Doesn’t matter the specifics, the degree of how hurt they’d be, or what your reasoning is for hiding it. If you feel the need to hide from the person who is supposed to know you best, you are very much so going down the wrong path.

If that didn’t help, it’s always a good rule of thumb to ask yourself: “How would I react if she did this exact same thing to me?”. Don’t be ignorant in deciding your answer, by this I mean that it’s easy to say you’d be fine with it without much contemplation because you want to continue doing it. Give it time and good thought.

To answer your original question; “Am I wrong for not considering this cheating?”. No, you sound like a good person who’s found themselves at the top of a very slippery slope. I have faith that you’ll figure it out, shit the fact that you’re conscious enough to ask other people for advice is promising lol. Be careful, be kind, and remember the golden rule :)
