I wouldn't consider that to be cheating, although your girlfriend might have a different opinion. You can either tell her about it beforehand or never mention it, unless she discovers and asks. What is important is that you have a clear conscience.
wound you care if your girlfriend went on a friendly date with a guy that might be attractive and didnt tell you? always always tell your gf what your doing especially if it involves a nother women even if its a friend. that will get a girl thinking real quit. but no cheating is when you kiss touch look or talk in a flirting manner or sexual manner
I don't think so but your girlfriend might. People have varied views on what cheating is. The only way to find out hers is to ask her & tell her about the date. If I had a boyfriend & he did that, I wouldn't mind unless he wanted her or she wanted him. But regardless, I would like to be told about this date. If it's friendly, then there is no reason why you shouldn't or not want to mention it to your girlfriend.
Always cover your a**. If you and this so called friend are going out somewhere wherever it may be it is not going to look right with just the two of you alone from her point of view especially if your attracted to her or the opposite in anyway. I don't know your age but remember this advise Think before you Do.
